While I am pleased to hear you think its better than Gmod 10 space map I think that it is more of a pro's and con's situation.
My map...
>Much, much larger for everything, distance, planets, ect.
>Much more detail for outer planets (the spheres have more faces and better textures)
>Terrain is flat and featureless (may change)
>contains all planets and more
Gmod version...
>smaller map
>space gravity is spherical in the sense that it extends out with a diameter.
>Life support mod, allows for construction of breathable atmostpheres ect.
>Terrain, has lakes and hills.
>contains most planets.
In the end, I think I prefer the Gmod version but its no longer updated and doesnt function that well anymore.
