- Wal-Mart has stepped up its quest for a slice of the used games market by rolling out a number of used games buy back kiosks.
Essentially the kiosks allow gamers to trade their old games for in-store credit so they can buy whatever they want.
To quote: You'll create an account that you log into every time you go to trade in a game to the machine and this account will presumably be accessible on any Wal-Mart used game kiosk.
There is also a slot to slide your credit/debit card; it's uncertain what role the card plays in you trading in games but my guess it's for some sort of accountability (who traded in what game, etc).
Once you've inserted the used game, the machine will print you a voucher for in-store credit. These kiosks, which accept PS2, PS3, Wii, and 360 games, are only in a few Walmart stores right now but seem to be working their way to more and more locations.
