Stars without number is made by Sine Nomine . There’s a free version and a paid for version . The differences between the free and paid for version are pretty minimal. I believe the paid for version has Robotics and AI. So if you want to get a good idea what it’s like, the free version is more than enough to figure out if you like it or not.
I’ve been creating blog posts for a Campaign Overview of my Stars without Number campaign and a running blog of the campaign itself. You can read all these posts in the Stars without number blog Category, which I’ll be updating as the campaign progresses.
