Which last gen titles WILL be rare??

[Deadman]

This topic could almost fall into the classic gaming category at this point, but I think technically it belongs here.

As I sift through bins of Xbox, GC, and PS2 games I see many titles that I've never seen before - even after 7-8 years of being in existence. Since the online rarity guide doesn't rate this "last gen" for rarity yet (other than a 0 or 1), I was wondering which games seem to be rare. Here are a couple of examples of games that I saw this weekend that I have NEVER seen before:

Freaky Flyers (Xbox) - don't have any recollection of it's release or any talk of the game itself. Looks fun though and my kids are having a good time with it.

Drive For Life (Xbox) - this game is all Volvo products and almost looks like something you'd get for test driving a real Volvo. The manual is almost a brochure for the car, discussing features and promoting the Volvo line, rather than gameplay.

Ford Bold Moves Street Racing (Xbox) - similar to the Volvo game above, but more game oriented.

There were a couple more including some GC games, but I can't remember them right now. So, the question is what games do you guys consider "rare" from last gen?

Also, if information on these titles is needed for the database (as the two car games aren't currently listed) I can definitely scan the boxes or manuals if that would be helpful!
