It is mostly a bookstore, but they have a pretty decent media section, and they buy back games, movies, music, and books.
PS2, PSP, X360, PS3, Wii, maybe NDS? Only had a couple of actual consoles. Selection overall was like I said pretty decent (I didn't find anything really rare or anything like that) - I'd expect the selection will pick up over the next few weeks as people start trading stuff in. It's worth taking a walk around that's for sure. Not to mention if you read at all, that place is hugeee.
