Back then:
Mortal Kombat / Street Fighter series, that was my childhood.
Golden Eye, Mario Kart, F-Zero X - Not one of my friends could even touch me in any of those games.
A lil while ago (3+ years):
My skills in the game of TFC was simply stunning, I was rather good at CS too, but that game was just to *blah*.
Tribes / Tribes 2 was also a game that if I was having a good day, you were not.
Now:
Absolutly nothing, I dont have the time to be that good at it anymore. I can still put up a damn good fight in just about any FPS tho.
