As Gamasutra reports, GameStop's marketing chief, Mike Hogan, supported the practice with an analogy, saying, "If you couldn't sell your old car -- would the [automotive] industry sell more cars?" Hogan went on to state that most re-sold games have been out for more than 90 days, and that 75% of trade-in credit goes immediately towards the purchase of a new game. Hogan stated that 20% of the new copies of Call of Duty: World at War the company has sold were purchased in part with trade-in credit.
Hogan admitted that "there are other perspectives, but ours is: trades and used fuel growth in the category." One thing's for certain: a game traded in for $12 and re-sold for $35 fuels growth in GameStop's wallet.
