Debate on For The People Play Balance
Topic: For The People Material
Over almost a decade the results from tournament play have had a more or less 50-50 win-loss ratio for each side. Here is an example of some responses to that continuing debate loved by gamers, play balance.
Baron, I think the fact that you state that the CSA has a measurable advantage and the post above it states the North is advantaged speaks volumes to me. There is no doubt in my mind that you are one of the better FTP players out there. As you know I speak from personal experience here.
The CSA can win early, but the Union has to win late and if it is not played precisely the Union can blow the win. My view is the CSA position is more forgiving of mistakes than the Union. I will note that in our second game, I made an avoidable mistake that gave you the game on the last card, which otherwise would have been a Union victory, but such is life (but a very enjoyable game).
My take on your CSA strategy is you put Lee in the West, dominate Kentucky and repeatedly raid the North. You support this with a strong fort position in West KY/TN. If you do not win by mid-1863, you use your interior lines to keep the Union out of the deep south as long as possible. The other important dimension is you try to keep close to sp parity by forgoing every offensive opportunity to spread out your sps to avoid attrition. All in all a very sound strategy.
I believe that there is strong Union counter play, and as always it depends on what cards you draw, but I believe that a prepared Union player has several strong counter play options. An aggressive Union amphibious strategy is key to create counterplay. The Union must create an sp advantage by reducing the CSA reinforcement rate. The maximum CSA sp production rate without cards is 15. If the South can maintain this rate for the majority of the game, barring unusual circumstances, they will win. The Union must conduct a game of economic warfare in order to reduce this rate. The best way is to take out the Transmississippi states and Florida, close down at least two blockade zones, and hopefully keep the South down to only KY until mid-1863. A reduction of 5-6 CSA sps gives the Union a 2-1 sp production advantage. If the Union plays an offensive game from mid-1863 through 1864, the South eventually runs out of soldiers. Its easier to state than it is to do, but that is the key to Union victory.
Also, I believe that wherever Lee is, is where McClellan has to be located. A McClellan/Pleasanton army on a fort is tough for even Lee with the dream team to beat in a large battle. All in all, I think personal play style determines which side someone is better with.
As far as you playing James in a long series, have at it. I do not think that it will prove what you think it will. Across the spectrum of games and players, the statistics are what they are. I take it from your statement that you think the CSA is a lock, you may get a chance to prove this in the next round. Good luck,
This is the kind of debate that I love to see. Thanks all...
I believe that Baron has put his finger on the key point. The sp ratio is a good metric on how the war is going. I agree that when the Union achieves a 3:2 or better ratio, then they are in the hunt for victory. This is why I advocate a strong Union naval game. Take a simplistic calculation, if the Union stops two blockade sps (combination of amphib and blockade drs), capture one CSA state (e.g., FL), and keep the CSA out of one border state, the South recieves 11sp versus the Union 18, which is one sp, Union favor, short of the 3:2 ratio. The CSA can expect on average 1sp per turn from cards over the course of the game. See below for why that is the case.
There are 12 CSA reinforcement cards of which they will on average get one every other turn, for an approximate average of 1sp per game turn over the course of the game. This gets the CSA to 12 (given the assumptions above) and the 3:2 ratio mentioned. The list of CSA cards is (Card#:No. of sps; ?=SW penalty for sps). #17:3, #21:3, #22:3, #23:2, #33:1, #37:3, #38:2, #41:2, #47:2, #79:1, #80:3?, #106:3
The Union gets 5 cards or two per game for an approximate total of 1sp every other turn.
The list of Union cards is (Card#:No. of sps). #9:3, #10:3, #30:3, #40:5, #43:1
Of course every game is unique and is strongly effected by the cards you actually get, how those cards are played, losses due to combat, and how the two sides respectively handle attrition, which on average benefits the CSA. CSA players who use the last card play to launch a raid every turn are usually gambling that they can win the game before the Union reinforcement rate buries them. An alternate tactic is to spread some forces out to make better use of local supply and reduce attrition, which the South often did historically.
These are the reasons why I continue to point out the importance of the Union naval game and offensive actions against small CSA states (e.g., TX, AR, FL and LA). If the Union can create a long term 3:2 ratio or better on the board, then the Union chances for victory are good, less than that and barring significant SW advantage, the Union is probably losing.
Hopefully this analysis will help explain my earlier posts.

Campaign Card Distribution
Topic: For The People Material
This was in response to a thread around Campaign Card distribution…
Great thread unfortunately based on one of our brothers experiencing campaign distribution syndrome (CDS).
What I would like to contribute to this debate is how I believe multiple CCs give an advantage, but are not a show stopper in it of themselves. I have had to think deeply on the issue of multiple campaign cards and over the course of time I have come full circle back to where I began in the AH version of this game, no CC limits.
It is important to note that there is a basic assumption that a skewed distribution of CCs is a decisive advantage. There was also a good point made that the Southern railnet and logistic conditions would have prevented this during the real war.
FTPs military model runs off of two key factors: maneuver and logistics. The Union won the war by prosecuting a persisting logistic strategy. The CSA was trying to win by prosecuting a raiding combat strategy. FTP is built around this set of assumptions and concepts as interpreted by me from a generic model articulated by Archer Jones.
The maneuver rules are expressed through the play of cards in combination with general ratings and board position. How much maneuver a side can sustain is based on its logistic position over the course of the game.
One of my goals when I did this game was to design logistics into the core of the system, so the players would abstractly deal with it without any mechanics. I focused on SPs as the integrated logistic system for the game.
The relative reinforcement rates of the two sides is the basic logistic production model for the game. The Union has a large and relatively steady rate of SP production and the ability of the CSA to impact this rate reflects a successful application of their raiding combat strategy. The CSA SP production rate is represented at a more granular level. If the Union applies its historic persisting logistic strategy, the South will reflect the historical collapse. If the Union fails to steadily take the Southern logistic system apart (blockade, ports, state bureacracy and manpower), then the South does not collapse. This is not the historical outcome, but neither is the CSA player achieving a more than historical level of logistic cohesion.
The attrition rules reflect operational logistics by causing players to disperse their forces at the end of a turn if they do not have a good offensive option. This is exactly what Lee did several times during the war for logistic purposes. If you spread out attrition goes down (broader access to local logistics). You stay concentrated, disease and logistic considerations wears your force down faster. Since the CSA usually goes last, the Union has to remain concentrated more of the time, simulating, without overhead many of the war's logistic dynamics.
What should and does happen is the ability to score on your opponent with multiple CCs requires that you have sufficient SPs to expend in combat and maneuvers. Without sufficient SPs having multiple CCs will not yield decisive results, just a maneuver advantage. Having a 10-1 advantage in CCs is possible, but without considering the context of relative SPs and board position, it is very hard to evaluate how much of an advantage this really is. The fact that Dirion has not yet put the Union away by this point indicates that he hasn't been able to fully capitalize on Taylor's CDS problem.
As far as the point that the South couldn't accomplish this during the real war, the answer is the game supports this under certain circumstances. FTP is a model of the war, but players effect the model. If the South is allowed to have a surplus of SPs, this is due to the Union failing to reduce the CSA logistic infrastructure. In this case the historical result is no longer valid for that particular play through, because one of the key historical factors has been altered.
It is true that the Southern rail network was inefficient and poorly laid out for military operations, but somehow the South was always able to pull off concentrations when they wanted to during the war. The game only has two strategic concentration cards (Shiloh, Chickamauga), so statistically in a standard game, the CSA should get two of these per game matching the historical record. However this is a simulation (game) not an emulation (book) of the war, so variation is both intended and desirable.
The bottom line is if you pay attention to SP management, multiple CCs can be very useful, especially to the CSA raiding combat strategy. If the Union works to first gain logistic superiority via a persisting logistic strategy as happened in the historical model, it will not matter much how many CCs the South gets late in the war, because they will have insufficient SPs (as they did historically) to do much with them. This inability to do anything useful with the extra CCs simulates late war logistic problems (Richmond calls for action, but not much happens).
The opposite also applies, in the late war when the Union can do alot with multiple CCs, since their reinforcement rate (logistics) is large and steady under most circumstances.
I hope that helps. I am going to look over the game in question just to be empathetic, but FTP isn't chess and chance plays a role in the outcome. However, unlike chess where no matter how many times you play Kasparov you are guarranteed to lose, in FTP hope can spring eternal; at least once and a while. James, one of these days...

Naval Rules Philosophy
The easiest solution to the Union naval forces is what has been used since Dunnigan's ACW game, which has been copied in every ACW Grand Strategy game, including VGs Civil War, in that you have naval counters that move on the river hexsides and have zone of control for a distance along the river.
What the player is then forced to do is arrange his boats like a puzzle until he has the optimal positioning that interdicts the river. I was looking for a more visual and less mechanical solution to this historical dynamic. My solution in a nutshell was wherever the Union naval forces could move unobstructed they had naval control. In a perfect situation, if there were no CSA forts, the Union had naval control everywhere. The CSA strategy would revolve around canceling, what was essentially a ubiquitous Union capability, by judicious placement of their interdicting forts, which is the kind of strategic decision they made historically. See my posted article for details.
The simple naval rule is the Union player has control over all CSA riverine and Coastal ports unless there is a CSA controlled fort present in the space (or associated coastal fort). There is a small set of cases that allow the CSA to deny Union naval control over a section of riverine ports if they can ENTIRELY block off Union naval pressure from ALL directions. One of those cases is the opening position in the game.
This is what the key rule states in the Design notes and case 1. Cases 2, 3 and 4 outline some of the other situations that can arise, which are all true at the beginning of the game for the CSA, but are hard to maintain thereafter.

More Naval Analysis
Topic: For The People Material
Amphibious Assault vs Forts
I would reference folks back to my msg 6732 where I laid out the designer intent and analysis behind these interactions. From a pratical point of view I went back and made a matrix of all possible situations just to make sure that I had it right. I will include that here, so the details are evident and then the broader way to easily rule on this should become evident.
There are two basic cases, ungarrisoned fort and garrisioned fort. With three exceptions, the outcome doesn't change whether there are 1, 2 or 3 Union SP. The results are written result versus attacker/ defender.
1-0: In this case the Amphibious invasion fails because the fort wins the battle under rule 7.32, and the Union loses 1sp.
0-1: In this case the Amphibious invasion wins, due to 7.32, the Union SP survives and remains in the fort space.
0-0: In this case the Amphibious invasion wins, due to rule 6.81, where the Amphibious invasion wins ties and has a surviving SP.
1-1: This is a case for ungarrisoned forts, where the number of invading SPs makes a difference in the outcome. If there is only 1 Union SP the Amphibious invasion fails, due to rule 7.32, and 6.81 does not apply since there are no surviving SP. If there are 2 or more Union SP, then the Amphibious invasion suceeds due to 6.81 since there is a surviving Union SP.
1-1*: If there is 1 Union SP, the invasion fails, because 7.34 does not apply, but 7.33 does, since there is a surviving defending zero SP. If there is 2 or more Union SP, the Amphibious invasion suceeds due to 7.32. The asterisk breaks the tie in favor of the attacker and there are surviving Union SP.
2-Any: This result is rare, but the Amphibious invasion fails due to 7.32.
1-0: The Amphibious invasion fails, due to 7.32.
0-1: The Amphibious invasion suceeds due to 7.32.
0-0: The Amphibious invasion fails due to 7.32.
1-1: The Amphibious invasion fails due to 7.32. Rule 7.34 does not apply because the defender is not eliminated due to the zero SP fort.
1-1*: This is the one case for garrisoned forts where the number of Union SP changes the outcome. If there is 1 Union SP, the invasion fails, because 7.34 does not apply, but 7.33 does, since there is a surviving defending zero SP. If there is 2 or more Union SP, the Amphibious invasion suceeds due to 7.32. The asterisk breaks the tie in favor of the attacker and there are surviving Union SP.
2-Any: The Amphibious invasion fails due to 7.32.
Broad Rules of Thumb
Having written this all out, there is no case where 1 Union SP can capture the fort (garrisoned or ungarrisioned) if it is eliminated. In the ungarrisioned fort case 1 Union SP can only win if it survives because the fort rolled a zero attrition result (only possible if the fort modifier is totally neutralized). The only times that having two or more Union SP changes the results is versus an ungarrisioned fort in a tie battle outcome (0-0 or 1-1) OR a 1/1* result AND a garrisioned fort where an asterisk result occurs, as in any normal battle. The first of these two differences is an important one since a 1-1 result is a common outcome in 2SP versus ungarrisioned fort battles.
I hope this clarifies and unknots this issue. I do not believe I have ever ruled differently, but this analysis covers all cases and is internally consistent.
The one extra point that I will add is the way in which 6.42 supercedes 7.33. This has unique situation and has no bearing on any of the fort cases. It applies specifically to when you invade a non-fort space that is defended by 1 CSA SP versus 2 or more Union SP. If the CSA wins the battle, but the CSA SP is eliminated, the surviving Union SPs retreat instead of taking the space ala 7.33, because 6.42 whereby an Amphibious invasion that loses is retreated, takes precedence over the fact that there are surviving Union SPs in the now vacant space.
I hope that covers the waterfront. Let me know,
Take care, Mark
Some additional thoughts...
I wanted to write a seperate addendum to the above case analysis that brings probability into the game. Some of the cases are not possible, but I included them to show the internal logic of the rules and for completeness.
Ungarrisioned Fort The only result that can usually occur is either a 1/1, 1/1*, or a 0-1. The 0-0 and the 1-0 cannot occur because any force versus an ungarrisioned fort gets a +4 modifier. Consequently, if the fort is not neutralized a single SP cannot win. If the fort is neutralized there is a 1 in 6 chance of a single SP taking a fort. If the Union has 2 or more SP then it always wins.
Garrisoned Fort There are a variety of situations here because there are many situations where the defender can have more than 1SP defending. Because of this all of the cases above become probable in some circumstances.
I hope that adds to folks understanding of these situations when they crop up in the game.

Wargame Order of Battle

Wargame Design Musings
I have been considering starting a blog. There are a couple of reasons, but the most compelling is it can be a place to collect my thoughts around game design in one place as opposed to distributing them across several message boards. Another strong reason is it is another thing that I haven't yet done, so it is another of life's little experiments. I will start with a post I recently made on CSW. I will spend some time collecting up from CSW some of my more important posts so they can reside in one location. More to follow as the mood hits me.
Some thoughts on OOB...
Consider this a random set of designer thoughts. I have seen a number of posts on numerous CSW and BGG posts concerning players perceptions of what an accurate game OB is or is not. My conclusion is that the common view is an historical detailed OB for a Pacific Wargame, although this thought process seems to cut across subject considerations, contains a minimum of a division OB, some special units, and all of the Capital ships. Based on this critieria EoTS is considered to have an ok historical OB, but lacks detail.
I would like to challenge this view. I would also state that an OB should be appropriate to how the units were used and the scale of the wargame. So, here is how I see it (it goes without saying that I have a parochial view on this, but who doesn't). Every ground formation at the Corps or Army level is included and carries the correct historical designation. All divisions that fought in the conflict are included within this structure that I feel is appropriate for a strategic game. I chose to show individual Marine units at the division level for the US and lower level for the Japanese as they were used in this manner. Plus, one of my design preferences is to show some of my favorite elite units (e.g., Chindits, Flying Tigers) as it adds to my view of the fun factor.
Every naval unit, including every DD, CL etc., is accounted for within the Naval TF groupings that I organized the naval forces around. I chose to show a couple of special naval units, such as the Tokyo Express surface unit (APD) and such as they operated independently for a significant portion of the war.
From my reading and analysis the Pacific war was dominated by land based airpower, so it is curious that this area of OB is usually not discussed. The one area that EoTS has chosen to include in the design with the same level of detail as the land and naval components is the air OB. EoTS does not use air SPs, but has each and every air formation included in the game at the Air Force, Air Flotilla, Air Division, level of detail. Where these air formations (not SPs) were located were a major strategic consideration during the war. I guess this is not an important component of an accurate Pacific War OB as I am not aware of too many other Pacific wargames that include this level of detail. To take a shot at myself, my Pacific War game suffers from the same issue, something I learned from and corrected in EoTS and will rectify in a future reprint of PacWar. I find it interesting that leaving this element out of a wargame's OB still allows the design to claim it has a more historical OB than another design. What I am not saying is that EoTS has the most complete anything, to include OB, but when others post their views and leave out the air element, I just find the logic curious...
I just wanted to get my view of what an historical OB should contain from my perspective.

For The People Material
Topic: For The People Material
This topic is a collection of some pretty deep analyses that I wrote for the CSW FTP topic. I wanted to collect some of the longer pieces in this location, so I can reference them when I need them.
I wanted to give some perspective on the FTP naval game. First off the tactics.
There are two situations ungarrisoned and garrisoned coastal forts. In the ungarrisoned fort case if the Union amphibious modifiers are 0 or +1 then 1 sp always loses due to 7.33A and 2 sp always wins due to 6.81. In this situation 3 sp is overkill. This was the basic historical model that I used. I could have made it possible for a more varied set of results, but there was no historical model to draw other results from. CSA coastal forts never held out very long unless they were backed by strong infantry forces. The two key historical models were the many small coastal actions, Ft Pulaski, and Ft Sumter (Charleston). If you throw more Union modifiers into the mix you can have a 16% chance of winning with 1 sp (because you cancel the benefit of the fort, so the South can roll a one and get a zero result).
The basic idea behind the CSA amphibious modifiers is that they reduce the Union chances of getting an "*" result in garrisoned fort situations.
If the fort is garrisoned, and the Union amphibious modifier is 0 or +1 then Union attacks with 1 or 2 sp always lose and the only probability is whether the CSA sp is elminated also. If the fort is garrisoned versus 3 sp, then the probability is 33% chance for success (force ratio modifiers are after amphibious, so they cannot be canceled - this is the Ft Pulaski model - a short siege).
If you increase the Union amphibious modifiers to 2 then you cancel the fort which brings in the 16% chance of a CSA dr of 1 in the 1 or 2 sp case. The 3 sp case gives the Union a 42% chance (doing this in my head, but its something like that).
If you increase the Union amphibious modifier to greater than 2 then a 2sp attack has a chance of victory, and a 3 sp attack becomes a very viable assault.
That is the tactical situation. The key to the naval game is understanding the tactical cases coupled with the Anaconda part of the game. Their are 12 blockade runner ports, but effectively there are 10 since Pensacola begins closed (I made it a marker for a future optional set up) and Ft Monroe starts Union controlled (and historically remained that way - although it can be recaptured by the CSA). The Union should try to close around one blockade runner port per turn to ensure shutting down the Southern blockade runner sps by the end of the game.
The South has three basic options for defending its coastline. The first option is to basically ignore it and use all of the sps it saves for other purposes. This puts the onus of exploiting the situation on the North. If the North doesn't do anything about it, the South comes out ahead.
The second option is to quickly garrison all ungarrisoned forts on gt 2 with a cordon defense. The only downside here is the South early in the game has alot fewer sps on their border which if the Union is aggressive can cause some significant early game problems. The South can also do this more gradually, but this leaves more coastline undefended longer.
The third option is the selected defense in depth. In this option, the South forgoes the cordon defense since it is equally weak everywhere and garrisons a key blockade runner port in each section. I usually favor Wilmington, Charleston, Columbus GA, and New Orleans. On gt 2 the CSA usually gets 13 sps which leaves me with 4 sp for coastal defense, since I can only rail 7 with two already up front in TN and VA. The basic idea is to get each of these locations with a garrisoned fort and an sp in its associated port.
If the Union attacks and captures the fort, the defended port prevents the Union from sending an easy follow up attack to get troops ashore deep in the South. If the Union attack fails, but kills the sp, then I use a 1 OC to move the port sp into the coastal fort to reestablish the defense. If the Union gets ashore at one of the ungarrisoned fort points, I will need to get a general with some sps to fix those situations. The goal is to keep one port per zone open so the only way to lose sps is through unsuccessful blockade drs which vary from turn to turn and game to game. If the Union doesn't aggressively pursue the naval option due to inclination or cards, I will gradually garrison all of my coastal forts.
Regardless of which plan you choose the Union will expend on average around 2 cards per coastal space to totally shut down all Southern blockade runner ports. This equates to around 20 cards (all 3 OC, Campaign activations, or Naval event cards). This number assumes that ungarrisoned forts take one card, ports with out coastal forts take 2 (one recapture each), and defense in depth spaces take 3. Obviously results will vary a bit here.
The Union will get 85 cards over the course of the game, so to accomplish shutting down the Southern blockade runner ports (when you include Blockade cards) equates to around 25% of the Union war effort. Of course the Union can use less cards than this to get good results from his naval campaign, such as relying on blockade runner cards alone, but that option varies in effectiveness from game to game (due to cards), so you can't count on it.
I hope this overly long note helps players to understand the historical model I applied to the game.
Good luck to everyone in the tourney,
