If you were ever a "fan" of High Guard, Striker, or the original FF&S, this edition is another in the long line of detailed rule sets allowing you to cover a great many esoteric aspects of ship and equipment design. If you don't like the way the standard technology works, it still gives you a good framework for adding in any other design sequence or sub-sequence to get what you want. Don't like Jump Drive? Prefer Bloater Drive instead? Just juggle the numbers!
The biggest downside to this volume so far is in the extraction. The PDF allows content to be sampled and moved (as I do with my games as they borrow from many but are based on a unique set of rules that cry out for having their content consolidated in a single rulebook).
However.... Every Odd page has a nice Imperial Sun symbol graphic overlaying the text. This interferes with your ability to copy text sections from all the Odd numbered pages. Whether or not it is a deliberate attempt to introduce some copy protection I cannot say, but since one of the main points of electronic documents is their accessibility... In any event, this cost the product 2 stars on my rating. If not for this, I'd have given it a 4/5. I've always been a follower of Frank Chadwick's game systems and Traveller was my first RPG, so I've got a soft spot.
3 for the overall product, +1 for the content, and â€“2 for the Imperial Sun graphic/watermark interfering with text selection.
