The major problem (aside from the ability of anyone associated with the game to answer simple questions about how zone combat works, despite direct contact with the developer) is very simple. The US can declare war early in the game for no penalty if they simply take the elective extra forces for the +5 PW hit, as by then PW is maxed out and there is, in effect, no penalty for declaring war immediately. Declaring war is a big deal, as it allows the US forces to take replacements, generate more reinforcements every turn, and it adds a ton of extra units to the US regroup pool. Plus all of those good US War deck events, and the US gets to determine who goes first every turn. More on why that's bad below.
How this could have gotten past the playtesters is beyond me. I suspect that some basic game mechanism got changed just before publication. Clearly, none of these people have ever worked in software or they'd know just how stupid an idea that is.
There are a couple of other problems, mostly that you can control PW through raiding, but there are only a handful of raid markers (a design limit). If you go first and play a 4 card, you are statistically due about three of the five raid markers, meaning a PW at the very least every turn. Plus that whole zone combat thing that involves interception by the active side which really isn't an interception as it's defined as being something that the non-active player does.
Add in a CSW header for the game that hasn't been modified to note that the game is released, errata that looks like it was cut and pasted from various forums without thought to organization, and a developer more interested in Easter eggs and too busy grading papers to have the time to respond to my questions, and I think I'll just put this one back on the shelf.
Hopefully this will be the last of the GMT disasters for a while. I really hope that with a cut-back production schedule that they'll start doing a little more QA of the games they put out. Because this one should never have gone out in this state. I'll admit that Paths of Glory did have that little problem with the MEF able to take Constantinople quickly with the right die rolls in it's early days, but that was fixed quickly by a veteran designer who answered questions. I think I'll just wait for the dust to settle, although to be honest the chances that I'll ever come back to this are pretty slim given how many other games there are to play. What a shame, this had so much promise.
