To be perfectly honest, I don't really see anything wrong with the becoming-a-rich-bastard ending, what with the whole exploitation of the alien world thing going on.
I'd like the rocket building to be able to launch satellites as well. Of the rain-fiery-death-upon-those-who-oppose-you kind. Or orbital building placement. That'd be so awesome
