Space settings allow game designers to break physical rules that ground-based games have to follow. Gravity can be reduced or reversed, tunnels can rotate around the player, and ships can travel in any direction without friction. This makes space especially well-suited to tunnel runners and physics-based games where ordinary movement rules would make the obstacles feel arbitrary. When a tunnel tilts in Run 3 Space or a car floats off a ramp in Galactic Car Stunts , the setting explains it — and the player accepts it.
