Eh...I have a PS-X, but I didn't like a lot of the games that were out for it. There is one I have called Sheep Raider where Koyote is stealing sheep from Sheep Dog. That was fun. And then there's Gran Turismo, which I never complained about...and Tomba brings back memories, but it didn't impress me very much.
I liked Sonic and Mario and Metroid (power to the original Game Boy!)....
I thought about getting an Gamecube for Viewtiful Joe. I've heard a lot about it. That and Super Smash Bothers: Melee. (Do the Kirby dance: <('.'<😉 (>'.'😉> )
PC...I haven't played much.... Star Wars Galaxies...Everquest...Diablo 2, but I think Half Life 2 makes PC gaming like Halo makes the X-Box. WoW and EQ 2 are pretty big addictions w/ my friends, too.
I have a Sega Genesis.... It was good for the time, but I think the PS-2 is the most rounded system. Unless it's super old school and then I'd go w/ Activision. Those are awesome, yeah. =^.^=
