what old games have you not played yet, but still want to get

around to playing someday?For me it would have to be psychonauts

and Beyond good and evil they both look like really good games and

good games should not go unplayed.

Oooh that's a good one.

I've got a lot. Lately when my wife is playing XBOX360 I've been going through My Genesis collection. I played World series Baseball for the first time last week and have enjoyed it a decent amount so far. It's the only baseball game I have that beats the 1984 Nintendo "Baseball" from my recolection. I haven't played Basebal STARS yet either but never did pick up a copy.
Next on the list is PrimeTime with Deion Sanders.

The Jak series, the GoW series, and SoTC.
