Mankind

Mankind is an amazing new game that opens a universe of possibilities! From a single ship, you can create a universe-spanning empire covering entire star systems! The game is real-time, multiplayer (only) through the Internet, in a persistent universe containing more than 900 million planets(!) The best part is that it is totally free to try out; check it out today!

Sadly, the developer of this game appears to have gone under and the game no longer works as of December 2002, possibly earlier. The website no longer responds and the game server is no longer available. Mourn the loss...
