Been playing it, but waiting for patches to come out to smooth out the game itself. Had it freeze and crash on me when I click on a certain ship in the campaign mode or crash when transitioning into a battle mode saying it doesn't have enough graphic memory.

comp setup
2.66ghz intel dual core cpu
2g corsair memory
512mb 8800gt geforce nvidia
250gb 7200rpm seagate
500gb 7200rpm seagate

all well within the recommended specs

otherwise AI can be a little dumb in battle mode but otherwise happy to go from a melee fest to a tactical game with all the new additions.

btw played sweden a bit, got world domination with austria(awesome line infantry) and currently bearing with poland-lithuania
