Evil Dr Ganymede has been examining and fixing the 2300AD star system generation rules (Part 1, Part 2). Very neat stuff. The “very hard” science approach doesn’t quite mesh with my setting assumptions – which are a bit more on the side of space opera and assume more garden worlds. I think once I am done looking at the Traveller system I will look if I prefer the 2300AD rules. Having entire systems would be nice, and perhaps terraforming could fix the low number of habitable worlds… I have to automate the generation process either way, since I’ll die of old age before completing it if I try to do it by hand. Hm!
