Wave Tron

Two cone shaped players start in opposite corners of a rectangular quadrilateral (along the diagonal). When a player moves slow, it creates a bow wave, and when a player moves fast it creates a shock wave. At slow speeds, the player naturally has a smaller turning radius than at high speeds, but the bow waves don't bounce off of the walls. However, at high speed the turning radius is larger, and the shock waves do bounce off the walls diminished into the form of bow waves. Bow waves can cancel each other out when they hit each other, or they can diminish a shock wave into a bow wave. The object in this game is not to run into the walls or not to run into the other players wave (or your own wave), but to get your opponent to do just that. (There might also need to be interior wall cubes and some other obstacles within the level as well to make it possible to change direction without running into your own wave.)
