Universe Sandbox is a quite unique and interesting interactive space game/simulator, which lets you create and operate "your own" virtual universe, control solar systems, stars, various celestial bodies, black holes, etc. It also allows you to see a large part of the universe and to explore outer space and celestial bodies, and control their behavior. This software includes our entire solar system: the Sun, the planets and their moons. It also includes the closest 100 stars and our local galaxy group.

You can travel through all these scenarios and use innumerable possibilities such as create a universe, play with gravity, time, speed, and even bowling with the moons if ultimately you want to do it. It is "god game" but, unfortunately for some people, it works on Windows only.

Installation is a bit complex, because your download results an installer which downloads the files that make up the program itself, but the file transfer is often slow and frequently interrupted, which unfortunately leads to various installation errors that force you to start all over again. The installer indicates a 38.5 MB download , but if you select the "direct" download (URL listed as mirror download), the resulting file is only 20.51 MB, which may be due to compression of the installer, but it was disconcerting for me.

You will receive a pair of 3D glasses when you buy it. You will also go beyond the 60 minutes limit.
