I don't think it will make Wal-Mart the leader of the used games industry by any means, but hopefully GameStop will be forced to come down on some of their used prices.
Also, not sure how much faith I have in getting a working USED game from a kiosk like this. I, like many people, like to check for disc damage, manuals, case condition before I hand over my cash. I don't really expect the games to be in pristine condition when I buy them used, but I don't want a disc that looks like it has road rash either.
Also, I can't wait to see the news stories about pot, etc in the game cases.
