I don't like the aim assist to be honest, leads me off as I'm about to kill someone.
The only real advantage I see for PC (and this is my opinion) is that it would be easier to record gameplay.
I'm not a fan of the aim assist either to be honest. PC's real big advantage is the use of a mouse. MW2 would have been a killer game for PC, but the lack of lean/dedicated servers just kinda killed it for everyone. I was originally going to get it for PC, but it's a direct console port and I found out there weren't going to be any dedi's
. All in all MW2 is only good on a console. Extremely fun to play with friends. AWESOME PS3 GAME!!!!!!!!!!!!!!!!!
