I personally like it but then again most people on here probably think im crazy for liking games like Pokemon Mystery Dungeon, Shiren the Wanderer Mystery Dungeon, Izuna Unemployed Ninja, Etrian Odyssey and other "rogue like" games. I personally can't wait for Final Fantasy Fables: Chocobo's Mystery Dungeon next month.
The difference between the Pokemon:MD series is that its easier and the death penalty isn't as severe as Shiren which brings you back to level 1 when you die and if you try to cheat from dying in Shiren the game save corrupts which forces you to start from the very beginning.
