[quote name='shivan128']I believe the SE includes all the gems as well as some extra costumes which could easily make up the $20 difference on the USED gamefly deal. Will have to pass on this. Wanted this on PS3... thanks anyway OP![/QUOTE]
FYI, it does not include extra costumes. Just a ton of gems, a really cool little bank, a different game case cover from the regular version that says Special Edition and has different art and a mini comic done by Udon that serves as a prequel to the events in the game.
Unless you want the extra gems and other stuff it comes with, I would just buy the game for cheap on Gamefly and then wait for the DLC to go on sale if you want any of it. Or if you have the money to spend you could just get the SF 25th anniversary edition box that will come with the game including the DLC and other games, movies, music, etc. as well.
