A star system consists of one or more stars plus whatever planets, comets and asteroids orbit it. Composition can vary a lot but for every star system there is a designated mainworld. This is almost always the most populous planet in the system, and will have this status for some good reason. Usually this means good habitability or resources, though there are sometimes other reasons why a world is settled. Where there is no obvious mainworld, one is usually selected based upon its relative position to the system’s primary (star). This might be an airless rockball in some systems, and another world could in theory be designated mainworld if the system is later settled and a different planet is chosen as the main location.

Written by fan-favourite M J Dougherty, A Guide to Star Systems is an invaluable addition to the Referee's Aid series, exploring the different systems of the galaxy and discovering how they can be used to influence campaigns.

So what exactly does this book contain? New tables for generating the rest of the the system, or purely suggestions of what else might be out there?

The book contains what I call "narrative" discussion of what is in a star system rather than science-based tables on how to generate the details of worlds and moons in a system.
Example: a very thin atmosphere is like being on top of Everest (0.3 atm pressure) - you won't die instantly, but you will get light headed in a few hours and need medical assistance.

Well, all of that is true, but I can work that out for myself being a science nerd (as most Traveller referees are in my experience). So if a prospective Traveller referee is weak at science then they may find this useful, but for me it was the least useful book I have bought from Mongoose.

Bit harsh to give it a 1 star review just because you personally didn't find it useful, isn't it? There are a lot of Traveller GMs who aren't "science nerds" (particularly when it comes to astronomy and planetary science) who would probably find that sort of qualitative discussion very useful.

As it is, I'd like to judge it for myself but the full-size preview isn't working...

Thanks Simon. Yes, Trav Ref's with H.S. level science knowledge would not find that very useful.

Now that you have bought it, you can give it your own rating to give a broader range of views. The whole point of a review is to show what I liked (or not) about a product rather than try and guess what others might (or might not) like about it. Because I have had such a good experience of previous books by Martin Dougherty I bought it despite the full-size preview not working, only to feel very disappointed.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
