GameStop announced today that it will be selling DLC activation codes for the Playstation Network in its European, Australian, and New Zealand stores. This kind of means that Sony is actually supporting players using trade in credits to buy new DLC for their games.
There’s no word as to why the agreement was limited to GameStop’s European branch, but it’s possible they’re just testing the waters. I’m not sure how much of an impact it will make though. While people with slow connections may prefer GameStop over a digital service for downloading games, you’re not actually getting the DLC from GameStop, just the code. It will be interesting to see if this partnership will actually give Sony a leg up in the DLC market or not.
