I decided to resume development of this map, as it looks like the most promising of all my abandoned projects. Unfortunately, the files seem to be missing from my computer. Here's hoping they'll show up.
I stopped progress last time as I was having difficulties making an environment that could be seen as realistic. A small, but medium to long range space vessel would need a power source and provisions for the crew and such. It grew overly complicated and so my work on the map petered out. I've figured out some ways to work around this, so if I find the files I will resume my work shortly.
