I want to launch spaceships and have a battle like Homeworld. I’m not a big gamer, but I liked the idea of full 3D strategy. Though, Homeworld had a lock-stop on orientation, which I think was a missed opportunity.

I've thought about adding a spaceship mode where you can pilot around the system you made, do gravity assists and such. The foundation is there!
