My local EB, now Gamestop, has given me and my friends more grief then its worth. They are picky with the condition of the discs they will take for credit, but literaly half or more of the used games my friend has purchased there end up not working. It's not the console, (360, Wii) because when he would finaly go to Game Crazy to buy the same game it would always work.
One time I called to ask how much credit I could get for some game and the
dude over the phone was bein all pissy and said they don't give credit estimates over the phone.
Just general jackassery from Gamestop, like its a pain for them to do their job. If they give you a game that doesn't work it's your bad.
At Game Crazy they buff my used games before they give them to me, if it doesn't work I'll bring it back and they'll buff it again or switch it for a different copy(for free). And they don't act like jackasses because they have to stop reading their magazine for 5 minutes and do their job.
Oh yeah, Game Crazy also lets you tryout any game in the store before you buy it, Gamestop(here) doesnt.
I know each Gamestop is different, but holy **** it sucks here
