DarkWorld is a space-based massively multiplayer real-time strategy game. Each player starts off with their own home planet. From there they can build ships, start exploring the universe, colonize other planets, and attack other players. What makes this game unique is that the game is always running at a very slow speed even when you are not connected. When you send a ship to another planet, it may not arrive for hours or days, and likewise the message it sends back may not arrive for hours or days. This allows many players to engage in a real-time strategy game that could last for months. New players can join the game at any time.
