Play a simplified version of tennis, but players are cars. (Or something else that means you don’t have completely freeform movement like in all other tennis games.)
The game simply uses the realistic physics engine. Your car has a flat top and angled sides, so you have to be smart about where you hit the ball to make sure it gets back across the net.
The main problem with these kinds of sports games is that everyone moves and hits equally hard.
This idea solves that by …
- Making movement momentum based (i.e. you’re a car)
- Placing powerups or things across the map that speed you up or slow you down. By placing a lot, you can find nice paths through them to modify speed
- Hitting the ball differently adds different speed, curve and direction.
Combining this …
- You are always moving
- You can only turn left or right
As a One Button Game
As an OBG, every car is simply controlled by 2 players.
This combines two OBG tricks in one.
- Cooperation/Control by putting multiple buttons on the same thing. (One player only controls forward/left, the other player only controls backward/right)
- Playing a sport through a car/silly entity, turning that simple thing on its head (like Rocket League)
