I enjoy Ps2 as much as any of them, and I have all three. There's not one I like more than the other, so far.

Nintendo rocks because the games are familiar to me. Zelda, Mario, etc.

Ps2 rocks because of the role-playing games it's kept in family. Until Final Fantasy crosses over to another system, I'm keeping it around. Also enjoyed Kingdom Hearts a great bit.

Xbox is kewl because of certain exclusive games. Of course, Buffy. That, and the hard drive is way nice. Don't have to buy a memory card, and will act on it's own as a cd player/dvd player. Not a great incentive to buy, but nice to have.
