This is the ONLY Pokemon spin off that worked well.

Game Informer was right about this game: it is fraught with bad design choices at every corner. Of course, I mean literally. Because the only bad design choice was that the dungeons are random! The rest, is as good as, if not better than, the other Pokemon games. The area of effect part of attacks is a great design choice, adding more strategy to the gameplay, and the ability to find items inside dungeons makes for more convenient healing, and the bosses are toughened up from being regular Pokemon to be like fully-fledged bosses. My only complaint other than the random dungeons is that ghost Pokemon are extremely powerful, as they can go through walls and attack you while you can't attack them. In fact, if you encounter one and you don't have the special items required to defeat them, you're pretty much dead. Other than that, if you're looking for a different Pokemon experience and you've had it with crap like Pokemon Ranger, look no further than Pokemon Mystery Dungeon.
