Well...
I USED to play WoW alot, but i got bored of it XD
Hmm...i like Warhammer, Warcraft 3 and Starcraft, for network-playing with local friends.
Wolf Team, too. Its gameplay is amazing. (shooter)
S4 League was cool, too. But it was FULL of hackers so i gave up on it.
And, well. I can't think of more atm. XD
