It lets you explore the universe in three dimensions, starting from planet Earth to the most distant galaxies' and is an app in the photos & graphics category. US 2 is not and that should be considered before buying. Space Engine Alternatives Space Engine Alternatives Space Engine is described as '- a real-time 3D space simulator, procedural universe generator and visualiser. That's probably the biggest difference of all though, US 1 is a finished game and works like one. The advantages the first one has over the second is probably better PC performance and signficantly cheaper.īut you know, like i said it is much more impressive visually and it's in alpha so you can kinda excuse the performance issues for now I honestly can't remember much of the first one now i've played the second one. If you want to fly through the universe, pick space engine. Universe sandbox is for playing around with the I reactions between bodies in space with some limited capabilities at the galactic level.
In general though the second one can do everything the first one can plus more and visually/graphically it's about 30X more impressive. The experience is different between both. Rather then give you the tools of a god like the paid version does. But i think it just allows you to view the simulations and change your perspectives. That demo version doesn't seem to be available on the official site anymore but there is a demo (free version) of the second one there. I didn't own the first one and only played a demo version of it.
