@professordead:
Hell yes! My SNES is back home in Pennsylvania, along with a few old NES systems, so I just emulate those two these days when I get the urge to play.
@Theo:
Hmmm, I haven't really heard of any of those, but I remember getting Shadow of the Colossus after many people raved about it, but it didn't quite live up to that hype. It was a fine game with great atmosphere, but it just got a little too redundant for me. I lost interest after the 8th(?) boss and never beat it. I'll have to go back and give it another go.
Another lesser-known PS2 game that I enjoyed was Shadow Hearts: From the New World, because it's quirky, diverse cast reminded me a lot of Final Fantasy VII. But somehow, I got away from that one, too.
One of the biggest reasons I want a 360 is for Fallout 3

@Paul:
Well, Crystalis is by far my favorite NES game, but I can't imagine anything ever being able to recapture the same magic that that game did. jRPGs are okay, but I prefer the ultra-mainstream titles like Final Fantasy and Dragon Quest. Anything else invokes too much of this image in my mind:

Anyways, I digress... It would probably save me a lot of money and be more practical for me to play all of these games on PC, but I really wanted to experience the social aspect of XBox Live with my friends and family :/ Tough decision...
