What was the first game you completely dominated?

[Cougarman]

super mario bros, i could beat the game without dying, i dont use the wrap pipes so my friends used to wait a long time.

first multiplayer game i dominated was World Cup Italia 90 on the megadrive/genesis, i was undefeated for a year in that game, no one dared to play against me, until my little sister beat me, i never played that game again, because i had lost my honor:P
