I currently have it set up as water
Why does it need to be land
I don't understand
In Final Frontier, space terrain is land (tundra, actually). This is so that space units can take cities.
Now, this isn't Final Frontier. However, there are two reasons for why it should be like that:
1. I'm using the same mapscript code. So, your first city will need to be dropped onto the center of the planet. But if space is water, you won't be able to build ships here, and thus you won't be able to go anywhere, because cities can't be built next to other cities.
2. Ships can fly over planets, right? Plenty of Star Wars battles have ships landing troops/bombarding targets... You should be able to bring ships onto planets and bombard the cities. You should be able to fight units over planets in ships. The only thing ships shouldn't be able to do would be to capture cities.
Ships should be like Civ 4 Gunships.
Ground units should be like ordinary units, except for the fact that they can't travel on space terrain.
Do you understand my idea?
