Jazzking2001 over at Neocrisis noticed an interesting development at his local Wal-Mart.  

Does it sounds so strange? Not really when you think about it, this is Wal-Mart after all. Most people are unaware at the moment, but Wal-Mart is now accepting used games to trade for credit.

Just a few hours ago, I went to the one near my house and was quite surprised at what I saw. Apparently they had a installed a new vending machine less than a day ago which allows you to trade in your used PS2, PS3, X-Box, Xbox 360, and Wii games.

The machine looks extremely similiar to the Redbox DVD rental machines. When I went to use the machine, however, it still had more than a few bugs that need fixing.

Ultimately the machine would not complete a transaction for him but it looks like Gamestop might have some real issues in the future. This will crush the used game market.  The rest of his post gives a description of interacting with the machine and bunch more pictures. Check it out.
