I have a friend who completely gets all of the stuff in the picture: the moon base, mansion and what-not, relatively instantaneously. I just thought it might be nice for players that far in to be able to do something afterwards, once they completely monopolize the planet.
I was thinking of having them buy another planet, for instance, and use their vast wealth to terraform the new planet, and slowly colonize it. They can begin investing in food production, housing, all sorts of things, and capitalize yet another planet! Maybe have it come after they buy every possible upgrade or something.
I don't know, just some musings I had while talking to my friend. Obviously needs some revision, but I think it would be fantastic to have this feature added.
