Lil' Lavery is correct in all respects except one and I'll take his word for Red Faction and the FF series, I don't have a PS2...or PS1. I just don't believe that Halo or Perfect Dark is that much of a stealth game...I like to be more blunt...or hollow-point I guess. A 90% minimum accuracy in PD can do that to you. My little bro owns the N64 though and he swicthed it for a Gamecube, so I don't get to play anymore *tear rolls down cheek*
Some of my favorite computer games though:
Age of Mythology
Chess for packard bell (Simple, difficult, not gawdy) (I ported it to my 'new', er, newer computer though, the packard bell only had 700 megs memory...)
Civilization III (its ok, not very customizable though)
Urban Assault (Not the commercailized version, a different game enclosed as freeware in microsoft game controller packages to test the joystick)
Alpha Centuri (program is done in notepad like UA...hmm...can we say mod?)
And Tetris...I still run that on an old Powerbook 180 (A floppy doubles its avalible memory

).
Steel Batallion for Xbox jsut has a cool controller though. Play it at a store but don't buy it. Its only a so-so game, but there's something about 3 foot pedals, 2 joysticks and close to 70 buttons including one for windshield wipers and ejecting that makes this mech game worth playing...
