United Kingdom gamers who live near Tesco stores can now trade in games for store credit.

MCV reports that at least 60 Tesco stores are taking game trades and offering the used games for resale. The chain’s newspaper advertisements are touting the program as well and noting the trade credit applies to anything in the store.

As Gamertell has reported, it seems that everybody wants a piece of the used game market. Not everybody, however has the genius behind the success of eBay Motors as part of their braintrust. Former eBay Motors head Simon Rothman has created a site called Glyde, which sells used games, books, CDs and DVDs. According to a VentureBeat report, 350,000 users are now participating. The site has only been in business for five months, so those numbers are turning heads.

Publishers and developers have long been unhappy that a week after a game’s launch, you can walk into a store and purchase a used copy for just $5 less than a new copy.

Electronic Arts is throwing a new wrinkle into things announcing it will charge for a “pass” to play its sports titles online. If you purchased the game, you will just need to enter the code in the box. If you have a used or rented copy, a pass will cost you $10. Tiger Woods PGA Tour 11 is the first game to have this feature (because Woods really needed some more bad publicity).

Retail giant Walmart is staking its claim on the billions of dollars to be made through used game sales, as it now lists preowned games on its site.

Used game sales and the game trade-ins that fuel those sales are a huge component of GameStop’s profits and other major retailers have taken notice.

The game retail market could be getting a little more competitive, if the photo of a recent Best Buy ad is any indication.

An eagle-eyed Cheap Ass Gamer reader in Utah spotted a Best Buy advertisement proclaiming the retailer would match GameStop and Game Crazy’s used prices on new games. Right now this may be a test to see if the program is workable on a larger scale.
