Last Fall I posted a quickie and general world generation system and noted I had an older one I used for traveller that I was updating to the 21st century. Some of it is here in this post, it's a big old mess of charts and a few notes, it's incomplete but I felt like sharing and wondered if anyone else out there would ever be interested in seeing more?
