Xbox360 and games appraisal?

No one can tell you, not even the employees. You have to bring the game to them. If they think it is not in good condition (even if it does not have a scratch) they can drop ten dollars off of it just for that. It has to have the case and instruction booklet. It also depends on how many copies of the game your store has or if they even want more. There is no way we could tell you. People may give you random numbers but you could easily get something completely different. When Left 4 Dead 2 came out I pre ordered two copies. I brought them back a few days later and one had been removed from the case only once and both were in great condition. the one that was more used got fifteen dollars more than the other.
