Gamasutra and Joystiq report that retail mega-chain Best Buy’s jumping into the used games market, nearly four years after taking the idea for a brief test run. Trade-in kiosks are being launched at several outlets in Texas this week, which — according to Best Buy CMO Barry Judge — verify the functionality of potential trade-in discs and issue store credit. Some stores (but not all) will also resale said trade-ins.

Yep, another corporate giant gets in on the used games profiteering biz. After all, what’s not to like? Give somebody $25 in store credit for a new game they bought a week ago for $60 and then turn around and resell it for $55 (marking it down a measly $5), while the hapless consumer (that is, the one you just fleeced) spends their store credit (plus some) on another new game. Rinse, repeat. This racket, in turn, deprives game publishers and developers of accurate sales data (not to mention revenue).
