I was just thinking.. how many planets do you know of that have asteroids around them (sans Saturn)... so why not consolidate some of the resource asteroids around planets into a singular moon. Of course some planets could have asteroids as is the case now, but wouldn't it be more realistic and a lot more interesting if some planets had moons instead of just boring asteroids? Possibly the resource balanace could be the same, but the mines would be constructed on different areas of the moon. So a moon could have 2 metal mines and a crystal mine. I just think it might be a bit more interesting.
Thoughts?
By the way, I'm sure this has been mentioned, but the bug where units will stop in the middle of a phase-line is incredibly irritating.
