on the subject of realism, i just don't think a 'super realistic' game is ever going to be very popular. heck, i had never even heard of the first arma until people started talking up the second.
people slam BF2 (for many good reasons) but the combat was pretty solid, aside from hitbox issues. there's a certain balance that has to struck between reality and what's fun. yeah, in real life i could shoot you from 200-300 yards with M16 sights, and an easy 500m+ with many sniper rifles. you could die from miles away with a guided rocket. but what satisfaction is there from being alive for a long while and then killed by an invisible enemy, only to have to repeat the entire process over?
i'd like to try this game, but i hated OFP and i don't think that's bodes well for this, even after (if?) the bugs are ironed out.
