Yeah, of course they do. You just randomly get shot and die despite being well hidden from enemy fire or on an RPG an enemy just will not let you hit it despite having all the necessary stats. I know I'm not alone on this. I understand that games have gotten harder over the years and that playing games on harder difficulties results in much more savage AIs but have you ever been playing a game and an enemy does something that defies the programming? Just kinda like the game is going around certain aspects of the landscape to seal your doom. It fuckin' pisses me off. I've heard people say "You're just mad 'cause you lost." Bullshit. I KNOW I'm a sore loser. But I know that there's something funny going on.
