Cosmogenesis

In Cosmogenesis you get the chance to create your very own star system. It will be your job to collide objects to create terrestrial planets, gas giants and stelllites. You will need to use comets to deliver the necessary material to provide a favourable environment for life on your terrestrial planets; just llike what happened billions of years ago with Earth in our Solar System. Or you could crash comets against gas giants to create a spectacular system of rings, similar to those of Saturn. Where will life develop in your system? Will it be on a homely little planet, like Earth? Or will it be on a moon whose skies are dominated by the majestic gas giant which it orbits?
