Halo 3 just keeps me coming back for more. It's one of those games that I just really love to play.
My GT is LORD MELBOURNE... however, I haven't paid the subscription in a while.
WoW was fun but a life sucker so I don't play that anymore... let's see..
MW2 Is pretty fun, but I'd have to say it's not that amazing, it's just sort of fun. It's basically the same as always. Too complicated for my taste, too many weapons, and so on. Halo is more simplistic, and, in my opinion, therefore more aesthetic. In an abstract sense more than in the sense of "I like their blood and gore better than their blood and gore." Lol.
I like Civ III the best though. I haven't stopped playing that game since it came out. Well I mean I've stopped but I mean, I haven't enjoyed it any less any of the times I've played, which is a lot.
Oh yeah and I'm a fucking master of Battlefield 1942. A little old school I know but I seriously wreck shit on that game lol 1st place every time, that kind of thing. So that's fun and so is Battlefield 2 but no one plays those anymore I guess.
