Though I began roleplaying in 1986, I had never heard of Traveller until recently.
More's the pity, in my opinon, for this game would have been an absolute hit in my group. Characters are simple to create, but the process is enjoyable. When I read this book, I think "I could run Dune in this." Or "Star Wars". Or "Star Trek, especially TOS". I could run less known sci-fi series, or make my own out of whole cloth and then easily stitch the game onto it. The true advantage of this system is that it has a toolkit underlying the assumed setting that allows you to hack it to other purpose easily, or you can default to the assumed setting for a game "ready to go" out of the box.
The .pdf is of decent quality. The POD is a good book, hardcover with black and white art (the occasional picture has a red feature as well). As profiled by another reviewer, some of the space scenes loose their sharpness, but the book is otherwise very readable. I also enjoy that you get a complete, playable game that is about 160 pages.
