Project Vague is a sandbox MMO environment in which players pilot space ships and travel a universe full of procedurally generated planets. Players will be able to harvest resources from asteroids as well as deposits located on the surface of planets and moons, which can then be used to construct bases and space stations.
If you're wondering whether or not this feels like driving an American muscle car all over the surface of an alien planet while searching for resource deposits to harvest: it does.
