This might work as a Flash game or a console game; it requires multiplayer.

The idea is that it’s an ordinary racing game, say like Burnout, Gran Turismo et al..  Or it could be a simpler top-down game like 4×4 Off Road or even RC Pro-Am way back in the NES days.  There is one player-controlled car in a “pack” of racers.

The point of the game is that there are four people playing at once, trying to control the car.  The controller inputs are put together in a voting algorithm that decides what input is actually used at every instant.

This could make for some interesting gameplay.  Racing is the kind of game where, if there’s one path that’s really good and one path that’s less good, a path that’s “between” those two paths will also be “between” them in terms of results.  The function is monotonic, in other words.  Of course that’s not true, but the areas where it isn’t true might be interesting.

I could envision a more skilled player trying subtle maneuvers and being frustrated with the less skilled players…However, at the same time the less skilled players are being shown more skillful ways to play the game!  A team of four really skilled drivers might be in perfect sync…or they might have completely different ideas of what to do!  In the end it might be the teams that work together well that will do the best.  (Perhaps a tournament mode with 16 players driving 4 cars?)
