Pretty cool
It's a great game if, like me, you can coordinate the approximate orbits of the planets you are given. Sure, the black planets have a bit TOO much gravity (and so you may have to make elliptical orbits), but overall everything else is great. What they need is more of an life evolution mode, whereas you spawn the planets, life may or may not evolve, and sometimes that life emcounters one another, and so on.
