According to philhassey, Galcon 2006
is a remake of an old DOS game. Imagine that you could send ships from Earth to populate other planets. Left click on a planet which your soldiers are currently occupying, then click again on a destination to initiate an invasion. Colonized celestial bodies appear on the star map in a bluish hue instead of the original gray.
Aliens from Mars can do the same as well, sending their fleet to invade other planets. Both humans and Martians engage in a race to conquest the stars and total domination or slavery.
Grey planets will put up a fight before submitting to a large force. Ships are automatically replenished, and the rate at which they are produced depends on the size of each planet.
