Okay, this is updated to a modern PDF format rather than being pure scan... so it's imminently usable now compared to some of the other books. You also have to remember this is a product of the late 90s, so the technology was different. Thanks to all who updated this.
Tribe 8 is such an intriguing setting, set in the ruins of Montreal. (Or, "Vimary"... a corrupted form of Ville-Marie, the central arrondissement of Montreal.) Spiritual apocalypse, death camps, liberation, where your players are children who descend from the survivors of the camps (disconnected from the world before). Really intriguing stuff. There aren't many games with this kind of world-building.
Of course, the problem here is that (outside of a few books and the very start of the metaplot), most of the rest of this line can only be found in used bookstores and scanned PDFs.
For me, I have virtually the entire line in hardcopy, including the entire metaplot, so getting a functional PDF of the core rulebook is just extra.
For new players? It's enough to get started. And what a start. Maybe you won't fully appreciate the metaplot without the books, but it's enough to build something in one of the most intriguing game settings to come from that era of RPGs. Even with the books, you don't need the metaplot campaign to make good use of the setting. It's that creative and different.
It's a setting that begs to be experienced. Get this one, the Vimary Sourcebook, and you're well on your way to having something good. It would be even better if the Tribe sourcebooks (Word of the Fates, Word of the Pillars, Word of the Dancers) were properly updated because those tell you more about building a Tribal cycle rather than a Fallen cycle, but the Tribe 8 Companion (which has been updated to a proper PDF) gets you most of the way to a Tribal/Vimary cycle on its own.
This game is mind-candy, and well worth checking out. Even today, people talk about Tribe 8. It's well worth the time.
