[quote name='video_gamer324']The newer the game, the higher the percentage you'll get. For new releases, you can usually get close to 50% back, but older games will only net you about 10-20%. And don't bother trying to get trade-in quotes over the phone. You'll have to bring the games into their store to find out exactly how much you'll get.[/quote]
Pretty much spot-on. The newest, most popular games will get slightly over 50%, and everything basically does down from there. There are some oddities, but not many...usually things that have high values on eBay. And yeah, don't bother calling. Most stores won't give TIVs over the phone.
