Counterstrike, but not source, 1.6. I've restarted to play it for 2 weeks now since I've quited playing it 2 years ago. It seems like I still got something, I've played on some servers in my country with some old pro friends. Too bad I will leave it again, but this is life.
I kinda hate counterstrike because even if I play pretty well I am nothing compared to what I was. I like Warcraft more, even if I stoped playing it for 4 months or so when I returned on battle.net I managed to win 5 games in a row, so....
