How much would I get for these games if I took these to Gamestop?

don't worry about if they have books or if the case it came in are in good shape. they have backup cases and the little papers that show the game covers they throw away because they want people to buy the new games of the version your selling. also you can just go to gamestop.com and look for the phone number to the place. you can do that but they will usually say "you'll have to come in so we can take a look at it.". bottom line make sure the game isn't scratched because they take 5$ out to fix that. the case, book and title paper doesn't matter to them.
