I have an xbox and a ps2. I think the xbox has better hardware (except for the giant controller) but the ps2 has better game choices. But xbox does have some cool games 'only for xbox', like my favorite, Halo.
Oh man, that really isn't fair. I loved almost every gaming system. (Although I have to agree with LOAF the 3DO was amazing!) I'll try to come back and vote when computers is up-and people have had some time to talk about it. I'd have to say I'd be leaning towards computers now-or maybe the SNES.
I'm going to pick up an X-Box after I get paid this week, but a system I really miss is the original NES. I got rid of mine about five years ago, and I regret doing that.
I have fond memories of playing various Mario and Ninja Turtle games.
