I dislike ship building and asteroid collecting, so this would seem to be a good option for me. But, was wondering w hat is the difference between this mod and AlchavX's Space Age Without Space?

This mod is basically the same thing as AlchavX's mod, but it re-adds the space elements to the game. Everything is available on Nauvius, but you can still build a space platform and visit the other planets. To beat the game, you have to get a platform to the edge of the galaxy. If you don't want the space aspects, just play their mod instead.

This is so much better than simply removing all of space :)
