3D not really used to greate effect. Could take years to finish a campaign. Beefy manual, long on historical details, short on game engine explanations.
Interface is pretty bad.
Lots of mouse-clicking. Unfortunately, the vast majority of gamers will be hard-pressed to find the fun inside this game. Instead they'll encounter a massive amount of detail that presents a challenge, but doesn't add up to an enjoyable experience. The Allies kick things off every turn with a planning phase. It's during this portion of the game that the clock is off and you can pore over every single decision.
