Solar 2

In most games you see stars in the background, you shoot asteroids or you live on planets. But in Solar 2 you ARE these objects! Solar 2 is an open-world, sandbox game set in an infinite abstract universe. Play constructively: grow your system, nurture life on your planets and attack enemy life in huge space battles. Play destructively: crash into other objects and cause chaos, use your orbiting objects like wrecking balls, steal planets from other systems. (store.steampowered.com)
