The idea is that a referee can use this (or the other books in this series) in his/her own universe to save some time when a more detailed world is needed. The referee can then change anything (e.g. the name of the planet or the UWP) to fit a planet in his/her own universe.
The planet Megara has a UWP of C9887B7-D. If you want to match it with a planet in the OTU, then maybe the planet Dakar in the Ilelish Sector is a good match. Dakar has a UWP of B9887BB-A. Any planet with a star-port between A-E, size 6-9, atm 8, hydro 8, pop 7-8, gov B, law 7-C and tech-level 6-D would probably work fine. It is actually impossible to create the UWP of Megara using classic rules. The tech-level is too high. But nothing in this pdf suggests that the tech-level must be this high. There is a maglev train, but that might be imported.
In this pdf, there are descriptions of the system with an image of the gas giant, and an overview image of the system. There are some general description of the planet Megara, and an isodecahedron map. Then there are some more specific descriptions of the planet and the people and cities and politics, and of the big herd animals called Betas. Finally there are a few adventure hooks.
What I would have wished for would have been some more detailed adventure hooks, an image of the Betas (and animal encounter tables), some notes on gas giant refuelling (since the gas giant is within the 100 solar diameters from the sun) and maybe some notes on the seasons due the the eccentric orbit.
There are also some other problems with this pdf. I hope Gypsy Knight Games (and other publishers) will learn from this constructive criticism and avoid such problems in the future.
