I've also heard that it's any game that has been on a nintendo system.

I have a Gamecube, last time I played it was months ago. It's a waste of space. I've got Metroid Prime, SSBM, and Super Mario Sunshine, and none of them are entertaining. SSBM was fun for about an hour, Super Mario Sunshine was a few hours. Metroid Prime is the only one of the three that I actually played more than a day, and I beat it and no longer have any urge to play it again.

Forgot to state my point. My point is, I'm not the only person that feels this way about the Gamecube, so I'm hoping Nintendo was smart about this new system. It seems like they have done a good job but until I know a few things I'm not sold on it either.
