What Chess is to medieval warfare, Homeworlds is to space warfare. The goal is simply to eliminate your opponent from their homeworld, while defending your own. A limited common supply of pyramids are used to create both star systems and spaceships, each color providing specfic powers in the game (red to attack, yellow to move, green to grow, and blue to transform). Monitoring the pieces available in the economy is as important as the moves you make on the table.
