The PS2 was(and still is) my favorite as it had many games of all sorts. action/adventure, platformers, fighting games, shooters, jrpgs, shmups, racing/driving sims, offstyle racers.
The Dreamcast comes in second with its large catalogue of shmups(Ikaruga, Border Down, Zero Gunner 2, Psyvariar 2: The Will To Fabricate, Mars Matrix, Giga Wing, Giga Wing 2, Gunbird 2, TriZeal, Chaos Field, Radilgy, Trigger Heart Exelica, Karous, Bang-Ai-Oh, Shikigami No Shiro, Shikigami No Shiro 2) and its wondrous ports of arcade fighting games (Soul Calibur, Street Fighter III: Third Striker, Street Fighter Alpha 3, Marvel Vs. Capcom 2) .
The Gamecube is in a close third due to Nintendo's excellent first-party titles(Metroid Prime, Metroid Prime 2, Super Smash Brothers Melee, Mario Kart: Double Dash, Starfox Assault, Paper Mario: TTYD, Super Mario Strikers, LOZ: TP).
As for the Xbox, well, let's just say that the Saturn is more appealing to me. I'm sure that the Xbox had some great games..........I can't think of any off hand, but I'm sure there must have been something....
