Can you trade in some of your games and gamestop accessories for cash? And how much would they give you if you turned in 1 used game?

You can but they have limitations to what will be cash and what will be GameStop credit. As for the used game it depends how old it is, they have a value calculator on their website.

Best answer is Kevin Jones', but to add to that, aside from the website you can also download the app and ther is a "Trade" section you can go to where you just type in the name of the game and it will show you how much you can get as in-store credit or cash.

They do take games. All depends on game what u get

Yes, you can. It depends on the game.
