Rotating Planets

They already rotate on their axis, but they don't revolve in orbit around the star. It'd be nice eye candy, but wouldn't really add anything to the game except an additional burden to your processor calculating the next position for conceivably hundreds of planets between turns.

Not just that. It would also make it harder to play, because the planets would be moving all the time. Also it would cause problems with starbases and ships as they would get hit be the planet if they stood in its path. Oh, and this problem kind of happens now too if you build a starbase next to a planet or a star for example a part of an economy starbase can get inside of a star.

I understand where you're coming from, just thought it would have been a cool idea. Though it does create problems with the game mechanics.
