Planet M.U.L.E

Planet M.U.L.E actually has had a long history. The original game was released back in the 1980s for the Atari 800 console. At that time, this was one of the few machines that allowed multi-player functions; featuring four ports. Today, the game has been remade with improved graphics as well as gameplay. Nevertheless, it stays true to the classics and ensures plenty of fun times ahead. The best part is that the game is offered absolutely free and works great on a Linux, Mac or Windows system. In the game, you play the role of a space traveler that's colonizing a planet. You'll need to use the planet's resources to make money and set up your colony. Certainly, a neat little game to try out.
