Today is the day future video game historians will mark as the apex of the battle over used game sales. It will take more than your online passes and one use DLC codes to intimidate Gamestop, publishers? You like single use codes packed in with new copies of games? Gamestop’s got your single use codes right here. If by here you mean the inside of every used copy of the game.

Yes, Gamestop is apparently offering the same bonus Catwoman content which should theoretically be the sole domain of mint copies with "pre-used” copies of Batman Arkham City, essentially making the whole code thing an exercise in futility. Questions such as where did Gamestop get the codes abound. Rest assured though, it’s not like Gamestop would take them from new copies in order to boost higher-margin used game sales. Then maybe sell those games as used copies as well when the codes run out? Although to be fair, their new approach of putting codes in used games certainly beats their old one of taking codes from new games.
