Planetoid 3

Planetoid 3 is a real time strategy game set in space, where you choose your race and expand your empire, build your economy, train fleets of ships and make war and peace inside a randomly generated solar system,

The game was considered to be in development and was available for download from the official website. The community was open, so you could join and suggest ideas, contribute resources, and help with the game as it was built. As of July 2020, the official website is down, and the Twitter account for the game hasn't posted since 2011.

Gameplay
There is only one mode in Planetoid 3, Freemode; you choose your race and set what kind of solar system you want to play in e.g. planet and moon amounts etc.. and then a solar system is randomly generated and you begin playing, you have two types of resources, Keldanyum and Energy, and you must manage your economy, and your people.

As you develop you are able to research new technology, build ships and eventually explore the solar system and colonize new worlds, and even trade, communicate, and war with alien races within the solar system.
