Here's my idea on implementing a galaxy-esque environment into KSP: I like the idea of procedurally generated star systems. The names of the stars could come from a pre-defined list (not that hard, I don't know how to program, and I've made callable lists in Python). The names of the planets around those stars could follow the name of the star such that around a star named Rigel, planets would be named Rigel a, Rigel b, so on and so forth, until you landed on said planet, plant your flag, and are given the option to rename it (or something like that). The next big road block seems to be the amount of memory tons of star systems loaded into KSP would take. Perhaps it would be possible to code such that once one exits a given star's SOI, only the star itself would be rendered, perhaps with a list of the planets in a right-click drop down menu. Basically there would be maps at varying levels of detail. One map view, like the current one, would show everything within a given star's SOI. The other map would be a Galactic view, showing only the stars themselves, with a clickable/hover menu detailing the planets around those stars. As for the actual design of the galaxy, I like the idea of keeping with the current trend of modelling after our own Solar system, but with it's own character. So a Spiral galaxy, even if it were only 100 stars and 20 light years across would be more than sufficient to keep even the most ardent player occupied for a very long time. Not to mention, if this tiered map view were possible to the galactic level, there is nothing to say someone couldn't then mod a higher order map, creating nearby galaxies. If I knew how to program/mod, I would start on this project right now.
