But yea... cars, spaceships and boats... if we can design whatever we want to race to navigate either the ground, water or air (maybe just ground and air for simplicity), we would really have a winning game. And obviously have balances... like different obstacles for each and benefits (power usage?). And all while doing it on a small planet. It doesn't have to be a conventional track either... maybe it could be to cover a certain amount of distance, or race to certain points on the planets, or maybe lap the circumference the globes a certain amount of times. Or all three for different game types. Holy crap... that would be awesome.
