To go back offtopic,
As a child i liked tekken (i played it with a friend who had a playstation (i had the N64), between luch break we'd illegally leave school to play it. (Naughty 10 year olds ^^).
An other game i loved (but in hindsight wasn't all that good) was mortal kombat. there was just something about the fatalities.
There was also a game on the snes i think, in which you got to fight with battletoads. It was fun seeing as you got to play it with two at the time against the great CPU enemies. Always a fun rivalry to see who hit the bucket first.
If we are taking crossgenres the games i had most fun with was Worms, Bomberman, and ... actually there are a shitload of games i had fun with. Doom wasn't one of them. never understood what made people like it so much.
