So, do you guys know if the developers are planning to add (or allow players to mod in) other star systems? I think it would be kinda neat to assemble a huge ship in orbit and then take it to another, distant star (especially if you could then stop at some alien planet and refuel it to continue your journey). While we're at it, wouldn't it be fun if they had a procedural universe so you could take your kerbals on an infinite trip?
The devs have stated several times that they aren't planning to add other stars. There's a user mod out there that sort-of hacks the game to add 3 stars orbiting a black hole to the game. But without fancy sci-fi engines to accelerate you up to a considerable fraction of light speed, you're still looking at several hours at max time compression to get between 2 stars.
