I think alot of people will say something different... So yeh, start a poll question with some titles in it if you want to know what most of us likes or something ^^
I pref Black Ops atm (better then nothing), waiting for MW3 & BF3 though..
well it depends on your skill level..
Combat arms ( good graphics. heck of alot of hackers ..skill lvl needed average)
Operation 7 ( ok graphics, hardly any hackers, gun customization is awsome, skill level average)
AVA( amazing graphics, pretty friendly players, skill lvl noob haha )
overally game you should try out is ava the guns feel soo good when u shoot them and thers no hackers at all( ok maybe some but they jst use chams no big deal)
