Sounds nice.
It's a lot of shooters/sandbox stuff, though, because those are popular.
If not mentioned yet, add vehicles. Vehicles move like soap in a whirl pool. The player needs to take each and every turn in a different way, even if they managed one turn and approach it the same way again, the physics have to screw them over and randomly bump the car into walls or launch it in the air.
