Don't believe your friends! The game takes REAL military to a whole new level.
The only problem I have with this game is the lack of customization and just overall games. After all this is a game, it needs more game modes - it needs more customization - it needs more player experience. The mulitplayer is just a simple | Heres a gun, put a scope on it and/or silencer/or damage bullets and go kill those guys. There is objectives but really all you do is just either hold the point or explode it.
Personally I'd save your wallets and wait for Black-Ops since the amount of customization and game modes that game is having makes it all worth the while.
Summed up:
MoH adds a great amount of good realism that the FPS genre needs but executed it way to quickly by not adding more customization or game modes.
