Re: Planets

There are some rules expanding the _Scouts_ system of world generation
published in the _Traveller_ supplements _Grand_Survey_ and/or
_Grand_Census_ (published by _The_Digest_Group_). These rules covered
local day length, possibility of locked rotation (day length same as
year length), orbital tilt (angle of polar axis) and means of computing
local (i.e. longitude and latitude) mean temprature from the other factors.

The rules (one book or the other, can't remember which) also suggested how
to create the continents of a world, how to allocate the population and
how to compute technology spread over a world (different in starport and
in the outback).

There is other things there too, that I can't remember right now, but they
expanded government and law levels, I belive. Great books for creating
consistent worlds, but that requires _some_ amount of work.
