*Worms
I played this game with friends for over a decade. It was funny, it required skill, it was often unfair, it was the best 'hotseat' multiplayer game ever.

*Doom
Pretty much the reason I got 'back' into gaming as a kid/early teen (I had stopped playing games for a while before i discovered Doom). I still prefer the 'kill lots of enemies' design to that of most modern shooters that focus on putting you against a small number of difficult to kill foes.

*Final Fantasy 7
The game that made me discover the jRPG. Not the greatest Final Fantasy, but the right game at the right time.

*Metal Gear Solid
It's not a game, it's an adventure ! An incredibly daring game for its time with some of the best boss fights ever.

*Warcraft 2
Played this for several years, the most fun RTS game for a long time (perhaps unsurpassed even now in terms of sheer fun factor).

*Vampire Bloodlines
Probably the only game I ever finished twice in a row.

*Phoenix Wright: Ace Attorney
Is it a game or more or less an interactive book ? Who cares ? It was fun and surprisingly refreshing !
