If the gameplay would allow it I suggest that some terrain features should be added, like craters and mountains. Unique structures could be built on each, like dome habitats on the craters and new types of mines for each. Different planet types would have different abundances of each feature, for example asteroids and lunar worlds would have lots of craters, and ice worlds and red planets would have a moderate amount. Maybe you could spend resources to remove the features by filling in the craters or plowing the mountains away.

I like this. Gives the game a more dynamic feel.

You could have bulldozer rovers harvest the mountain, and Filler rovers fill in da craters.
