Cosmic Encounter

Players represent alien races that are seeking to spread themselves onto five foreign worlds. To accomplish this, they make challenges against other players and enlist the aid of interested parties. But alien powers, which are unique to each race, give players ways to bend or outright break some rule in the game.

The game continues until one player occupies five planets in other systems to win. Shared victories are possible, and a player need not occupy one’s own system to win.
