I just went today to look at trading in stuff for an Xbox 360.
I can trade in epically terrible PS2 games like Shrek 2, Shamu's Deep Sea Adventures, American Chopper, American Chopper 2 Full Throttle, Ty the Tasmanian Tiger 3 for $33 each however they wont take good games like GTA:Vice City. Really odd IMO.
I couldn't talk my sister into going halves with me though so I wont get to DOA4 till I get a new job.
