No technical problems with the PDF. This product gives background details for the Crusade series, and adventures set during that era. Obviously, being 1st Edition, some of the game mechanics have been superceded (the 'Linguist' feat, for example) and other game mechanics would need to be adjusted.

The first few pages give bios and game stats for the Crusade regulars, and a few B5 characters that appear in A Call to Arms. The next 80 pages or so are synopses of the TV episodes with some suggestions on how to use the ideas in a game. As with the other 1st Ed. season guides I found these to be of questionable writing quality and of minimal use. Of interest to B5 fans, however, is the inclusion of the three unfilmed episodes - To The Ends of The Earth, Judgement Values and The End of The Line. The scripts were once available online, but have been unavailable for years. If you want to know the direction Crusade would have taken, these are worth a look (although maybe not worth the price alone).

This supplement is quite light on game mechanics. One new race (Dureena's species, the Zanderians). Three new feats, using strange mechanics that I think are obsolete under 2nd Edition. Two prestige classes (Doomsday Cultist and Master of Subtlely, i.e Guild Thief). Again, of limited interest and innovation. The stats for the Shadow Death Cloud and Drakh virus are updated in the excellent Drakh supplement. Of more interest are the details of the Bureau of Telepath Integration and how this now works, also of interest to B5 fans (although I'm uncertain of its canonicity) is the background story of the Apocalypse Box. The book ends with a detailed look at the Excalibur - game stats superceded by the 2nd Ed. rulebook. it would have been nice for a deckplan, even if just an overview. This, I think, is symptomatic of Mongoose's "rush 'em out" publishing philosophy that tends to neglect the value-added stuff (if I may stoop to business jargon).

Overall, this book is worth getting either if you are a Crusade fan and you want to read the unfilmed episodes, if you want to find out about the BTI, or if you want more information on the Apocalypse Box. The rest of the stuff isn't really anything a good GM couldn't fathom on his own with a set of Crusade episodes and the rulebook.
