I picked up a copy of ArmA II yesterday, I'm a big fan of Operation Flashpoint so was quite looking forward to this release, I have to say this game is utterly incredible, the sheer attention to detail is amazing.
I found this review that describes the game far better than I ever could, I think it sums up my thoughts on the game perfectly :
http://www.videogamer.com/pc/arma_2/review.htmlI don't think I've been this interested in a game since BZ2 , it's got everything, realistic combat, strategy, some of the multiplayer modes sound very cool indeed, once I finish the singleplayer I might do some online gaming for the first time in years - 50 players at once each with a battalion under their command all fighting it out on 225 square Km map sounds too awesome to be true.
