Well nintendo power has been saying that this game Shantae:Risky's revenge is a must have, and theres also this game that I think looks really cool called photo dojo where you take pictures of you and your friends. Then you make those pictures sprites and have them fight each other. It looks REALLY cool so you might want to try that.
