Depends on which ones. There are Game Sharks for all kinds of consoles. TRY PLAY N' TRADE They sell used games, used consoles (like Atari's and Dream Cast's), they are so much cheaper!! I got Final Fantasy XII at Gamestop for 14 bucks. I got the Limited Collectors Edition at Play N' Trade for 4. Did I mention that Play N' Trade workers actually know what their talking about?
