So we got naval units, land units, air units and giant meteors that can impact the planet. But what about getting to the planet? Will their be any space based combat?
Most you get for space combat is around planets and moons astroids Their will be no space combat in middle of nowhere that is pretty much all uber has said so far.
After thinking about it I can really see why too. The vast majority of space, even in a solar system, is just empty void and not a very interesting landscape to have a fight on. But once you get into orbit around a planet or something you have a tighter space with more going on, you could have orbiting space junk, ion storms, orbital platforms, dust clouds or asteroids in the Lagrange points. And you have to worry about where you are in relation to all of the things on the surface that you can interact with. You could say that radar range is a sphere instead of the SupCom blue circles of old, so if you know they didn't have radar coverage on one side of the planet you could do staging there and work towards their base. Then you have to worry about being over buildings that can shoot at you, or buildings you want to shoot at. And if you have transports you'll probably want to fight your way to a spot in space above where you want to land. Also I'd guess that from a coding stand point it was probably a bit easier to say "Each planet is a map with 4 layers. And their distance in space only really determines how expensive (in time and resources) it is to get units from one place to another."
