The goal of spacesim is simulation of a battles in free space. Unlike other such games, spacesim models management of the ship from the point of view of the captain, instead of the pilot. It allows management of the ship of several players at one time.
QuantimSim is a physics simulation engine. Some aspects of astrophysics, electromagnetism, relativity, thermodynamics, statistical mechanics and quantum mechanics will be included in the simulation library.
