I am an avid reader of Rock, Paper, Shotgun and they had an article there a few hours ago about a game that was literally just announced (the forum has 3 threads in it!) called Spacebase DF-9. The creator is actually interviewed and mentions Rimworld and PA in it. The game looks really great and it seems very similar to RW, but distinctly different. They want to tell a story, but they're also wanting to do what DF does with their complex systems or so that is how I read it. Check it out.
