Game Crazy also noted that you're more likely to receive more money on your trade-in if you're quick about selling it. "Just like a car, a game’s value decreases the older it gets, so the sooner you trade games after purchase, the more value you will receive toward additional purchases. For example, the trade-in value of UFC Undisputed is $25.00 today, but it might be down to $20.00 a week from now. Therefore, Game Crazy recommends bringing it in as soon as possible, even if the consumer isn’t sure what game they want to use the credit toward, and saving the credit on a gift card," the retailer said.
