Yes Gameware takes used games. I try to buy new games there as much as I can because they are a mom and pop store and they seem to really care about good games vs. selling whatever the flavor of the month is.
I've actually had them tell me stuff like "yea, we just got that game in... but don't waste your money... it SUCKS!" Not the managers, mind you, this is the employees talking!
They import games, import systems, and most of their arcade cabinets are imported as well. Anyone in range should support this store and stores like it unless you want to see more huge corporate gamestores dominate the world.
Hell, where else in town can you get a few sessions of Guitar Freaks and Beatmania in?
