When buying a game online I prefer to buy the game that comes with everything including the cartridge/game disc, case, and booklet/artwork so I can have a bookshelf to put the game at. I don't like to buy used games because it may not includes the case and just the game only. If it's before the 6th generation of gaming like before the nintendo gamecube and nintendo ds then I would buy it with the cartridge only because it's old. Plus, the used games might not even work good or may have something wrong with it.
