I will have to say my first FPS was Perfect Dark (n64) Action, Supersmash Bros (N64), RTS Empire Earth (PC), MMO Guild Wars (PC).

goldeneye, bloody roar (maybe mortal kombat, I forget),command and conquer, and I forget the rest.

I think Combat or Space Invaders was my first game ever, on the 2600 Woody ^_^

First FPS was Goldeneye
First Online FPS was Counter-Strike
First RTS was Age of Empires
First MMO was RuneScape
First Action was SSB (The original was and still is the best in my eyes. But maybe I think so because I don't own a Nintendo product past the N64, and don't plan to. But I have played SSBM before with friends. I wasn't too impressed.)

First game that I ever actually played was Mario Bros. for the NES. I guess that makes it my first platformer too.
First game that I owned was Donkey Kong Country for the SNES.

Action - Doom (PC)
Racing - Outrun (and the first game i ever played) (Sega Saturn)
