WorldGen is a world creation tool designed to generate a living universe of stars and planets for use in a Science Fiction RPG similar to Traveller. When it was originally written over ten years ago, it was designed to directly read UWP data and simply expand it to include multiple planets per star system. The latest version is currently focused on building systems from scratch, with no concerns as to the UWP. However, the style and flavour will be similar to the Imperium, though not identical.

Specifically, as the example below shows, the amount of information generated for a world is considerably more than can be encoded in a UWP.

At the largest scale, the galaxy is split into Sectors, each of which is 32 parsecs wide and 40 parsecs tall. Sectors are numbered from a central location, spiralling out in a clockwise fashion. The galaxy is two dimensional for reasons of simplicity.

A star system normally consists of one or more stars plus a system of planets. It is possible for a system to consist only of a single rogue planet, or several stars with dozens of planets, moons and asteroid belts.

Planets make up the bulk of the data. They are classified according to the Planetary Classification List, which determines the broad characteristics of the planet.
