Game Design Challenge shows reader ideas for 3DS games

Shadowplay is a 2D platform puzzler that uses the shadows of real-world objects to give players “puzzle pieces” to complete levels so their characters can platform through them with ease. Shadowplay utilizes the 3DS’s 3D camera to capture object models and the 3D functionality of the system to give players a powerful light manipulation tool to play with. Ultimately, Shadowplay invites players look at their world from another perspective and to integrate both worlds into an entertaining experience

These are not 3DS games that are going to be made, but instead, a bunch of ideas pieced together by people that entered the Game Design Challenge. Check out some more winning entries here.
