Wunderling DX is an interesting take on the "villain becomes a hero" concept in that you're basically a minion setting out to stop the hero.  While I can see some players may be turned off by the simplicity of the game and the easiness of the early-going, there's enough content and collectables to keep things fresh throughout your journey as an underling setting out to stop a hero.  As backwards as that concept may seem, I thoroughly enjoyed my time through Wunderling DX.
