Your first planet. Generally, homeworlds start out with quite a number of colonists, minerals and cash. Homeworlds tend to stay the strongest planets throughout the game, otherwise they are not special in any way (except if you play a scenario with a goal like "capture your neighbor's homeworld", of course).

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
