Whoa this seems pretty hectic :O I didn't even know stuff like this was going on. So what? It's like super-realistic and stuff? I mean, doesn't that take out the "fun" factor? I mean, in a Flight Simulator vs Ace Combat sense.
Arma is Battlefield on steroids. Its pretty tough because of its realism eg. 1 shot kills depending on where you are shot, your soldier gets tired from running around alot and pilots black out from pulling to many G's etc.
Despite its difficulty it is super fun though, the game gets better as you get better.
The games amazing, its actually more than a game I think.
