Universe Sandbox

This hugely impressive gravity simulator game founded by Dan Dixon nearly 18 years ago has jumped leagues since I first came across it in 2008. It predates the hugely popular Kerbal Space Program and is definitely for the more discerning astro-physicist. The newest version of the game has been re-written in Unity, a Direct3D and OpenGL utilising library. I am currently developing a project that may be able to piggy-back the project as an MMORPG, so watch this space on kickstarter.com!
