I've been coming here for a few years. I don't have to buy it brand new to have fun. I'm on a budget. I explain that to them and what kind of games I like and they give me a lot of used games to choose from.
I've never bought anything on their recommendation that I regretted. Even if I did, they have that money back or equal trade thing (for 7 days I think). I've never had to use it. I like this store because of the employees. If it weren't for their friendliness and knowledge it'd just be another game stop.
Hint - if you're not sure what you're lookin for, tell 'em what you like and your price range and they'll show you some good selections.
