GameStop is rolling out an all-you-can-eat subscription service for its used game inventory, according to an advertisement spied in a magazine over the weekend. Under its terms, subscribers can pick any used game, play it, return it and get another as often as they like.

Moreover, players can keep the last one they take. Polygon has emailed a GameStop representative for more information on what that entails.
