How is the replay-ability of Super Mystery Dungeon? In Shiren the Wanderer, they kept opening up newer harder specialized dungeons, or I assume they kept opening them up, I never made it all the way through the cooking dungeon nor did I solve the puzzle dungeon all the way... I suppose those are poor examples if you never played the old DS title, but in Gates to Infinity I don't recall much from the story after the first run through, so other than customizing your own personal paradise, I don't recall there being anything else to keep bringing me back.
