Universe Sandbox 2 An excellent space simulator!
Universe Sandbox 2 is a simulation game that allows players to create and manipulate entire star systems and galaxy clusters. It is not currently a game in the traditional sense because there is no real fail state and no goals that the players do not make themselves. Players start with an open universe. Menus are then used to add different celestial objects to the universe such as stars and planets. The physics are applied realistically. This means making small modifications to a star system could cause massive changes or impacts between objects. One issue with Universe Sandbox 2 is that it is currently incomplete and lacking some promised features.
