Hey, just stumbled in here. Nice to see somebody used my galaxy tute for the same purpose that I had in mind. I'm designing a SF RPG and needed a galaxy so that's why I came up with that tutorial eventually.
Here's the first version of the galactic map. Many of the worlds shown are already decided but this map is now out of date since I want to re-position worlds and sectors to conform with the storyline and probably give it a whole new look.
This is actually quite a lot influenced by the Star Wars galaxy but I want to distance myself from that again so it really reflects my own IP.
There's also a sector map which is a WiP of a sector map that is used to show several of the sectors on the galactic map in more detail. The navigation system will zoom in from the galactic map down to any single planet step-by-step: galaxy map -> sector map -> star system -> planet.
I know it sounds as if I'm just copying Mass Effect here but I actually had the idea for this already about 10 years ago.
Either way I hope this will give a bit of inspiration to others.
