Planet Types

This post is mostly for my own benefit. There was a post on Porky's Expanse that I forgot to comment on; it's an alternative scheme for describing planets. Since eventually I will get Liber Zero finished and can move on to my atomic age horror and space exploration game(s), and since I do get regular hits from people looking for a planet generator, I want to remember Porky's post for future reference, when I get around to improving my own planet generator.
