The huge convenience store chain has announced that it will be entering the game retail market. If you have been to 7-Eleven stores in North America lately, you may have noticed that stores now carry big-ticket titles like Guitar Hero and Fallout 3. But these selections are only available “while supplies last.” 7-Eleven’s announcement changes all this by committing to carrying more titles, now just bestsellers, and making games a regular stock of the store along with its hotdogs and Slurpees.
