The game sold by people the most? The game bought used the most?

[Pyramid Head]

It'd be awesome to see what games were chopped the most to stores, and which games people bought used.

Not sure if anywhere would actually have that info aside from game store company databases.

Prolly see some surprising stuff.  This gen I've seen more Forza 2s than anything else aside from maybe Ghost Recon.

Is there any real stats on this stuff?
