One game that you will never see outside of Ebay is World of Outlaws:  Sprint Cars 2002.  If you pay less than $50 for it, go buy a lottery ticket because you have some heaping portions of ethereal assistance guiding your life.

Found that one at a pawn shop for $6, didn't even know that it was rare.

Here is an ebay link for a complete copy for $19.99 buy it now.

Fallout: Brotherhood of Steel is starting to be tough to find. Not really rare (yet).

And Beyond Good & Evil has a real cult following. I'm thinking it's going to start going up in value soon because I haven't seen a CIB copy of it in a LONG time.

Pikmin II is pretty low print run too, so I've heard.

It sold over a million copies and they have a greatest hits version. Its pretty easy to track down, just has a high price tag.

Fall out for Xbox is still everywhere here as is Beyond Good and Evil(still in Walmarts actually).

Over all i think GCN is the hardest to find games for in general. It has always had a VERY small selection in stores compared to the other consoles. Even when it was new.

For the PS2, Rez is hard to find (I've been looking for a copy forever) and I've heard that Disgaea:  Hour of Darkness, Guitaroo Man, and Mr. Mosquito are hard to find, but I have Disgaea and Mr. Mosquito (and it wasn't too hard to get them) and I've seen Guitaroo Man a bunch of times at Gamestop and EB.  One game that you will never see outside of Ebay is World of Outlaws:  Sprint Cars 2002.  If you pay less than $50 for it, go buy a lottery ticket because you have some heaping portions of ethereal assistance guiding your life.

Marvel vs Capcom 2 for PS2 is rare. I picked up a copy with no manual for $15 at a pawn shop. Ebay tends to hold strong to about $80 for that game with no manual.

I found Rez and MvC2 on complete flukes at Gamestops. Rez had a $50 used tag, and MvC2 had an $80 used tag.

Painkiller on X-box is nigh on impossible to find in England at the moment.
