Mario Kart clone, anyone? This engine could be used for one. Its main problem is speed. It would probably be exclusive to the New 3DS or Wii U. Wii U is probably the only one that could reasonably run it.
Sure, the maps, I could probably do the sprites. Try to get at least the first and second maps from the mushroom cup or better yet make a clone of it. I'll see about the sprites.
