CHILDREN OF THE BLOOD is a supplement to CULTS OF THE BLOOD GODS and a stretch goal for its Kickstarter. Basically, it is a book of NPCs (or SPCs as White Wolf is now styling its terminology) as well as some rules for running cults in the World of Darkness. It is a spiritual successor to CHILDREN OF THE INQUISITION, which was a book that provided some important power players like Dracula and Etrius during the early days of the line. It actually reminds me a bit more of CHILDREN OF THE REVOLUTION in that it is a bit less overt in the importance of the NPCs that it presents.
I am a stalwart defender of Vampire: The Masquerade 5th Edition. I believe it is the best edition to come out since 1st Edition and the original Chicago Chronicles. However, I'm going to be honest in that I also feel like it is best done by Onyx Path Publishing. The two best things to come out of 5th Edition so far have been the LA by Night web series and Chicago by Night as well as its supplements (The Chicago Folios, Let the Streets Run Red). Well, only the latter is a game supplement and by OPP. OPP has already an established reputation for making awesome supplements for the World of Darkness (Beckett's Jyhad Diary is my all time favorite V:TM supplement period) and just "gets" the material. But does their latest supplement continue this trend? I'd say yes. It comes with a few minor caveats but it is definitely top tier material for the setting.
LET THE STREETS RUN RED by Onxy Path Publishing is a collection of four Chronicles for Vampire: The Masquerade 5th Edition. It is a stretch goal from the 2018 Kickstarter for Chicago by Night 5th Edition, a book detailing the supernatural movers and shakers for the Windy City. Basically, for non-tabletop roleplaying gamers, it's a book of four adventures to play as vampires. I've been waiting for this book for a long time, specifically two years, and I'm extremely excited to finally get to dive into its complicated adventure hooks.
