My guess is, you'll have to secure the space above before you move to the surface.
But that's just a guess, from thinking not to over complicate the gameplay.
I'm thinking it might be somewhat in the line of Imperium Galactica.
I liked that game, and wished it would be set in the Star Wars universe.
I actually hoped Rebellion was gonna turn out like that one, but I was alittle disappointed it wasn't.
Still, that was a fun game. A small feature I liked about that one was the ability to name my star destroyers.
My hugeass starship list came in good use there.
It even grew as I dug up more and more names from the Star Wars Universe.
I actually hope they insert this small feature into the game, gonna make me love it that much more.
