The latest rumors doing the rounds promise the “BrB” is coming for Age of Sigmar. Here’s the details:

Regarding a “Big Rulebook” for Age of Sigmar:

“I’m hesitant to call it a “Summer Campaign”, because a majority of the bigger stuff will come out after the summer is over, but the big new

selling point of AoS is going to be vast narrative campaigns and story arcs. The Realmgate War is going to be the first of these campaigns. Future campaigns might be more focused, but RgW is primarily going to a walking tour of the new setting. The release pattering is going to be formulaic: Here’s the new world (Sans Azyr and Chaos, we go to them during the final), here’s the evil force that’s making everyone’s life awful, here’s the good force that’s going to liberate them. Inky, Blinky, Pinky, and Clyde each get their own named faction, and The Horned Rat and Nagash will each get their respective 15 minutes of fame. Once all the new factions are introduced, and the war scrolls proper are put up, that’s when we finally get the BrB. Don’t think of this as 9th edition, think of this as the first expansion to Age of Sigmar. It’ll be much smaller than a core rulebook, but larger than a codex, and will look and feel a lot like the Horus Heresy books from FW. There will be rules for list building, missions, campaigns, as well as all the “advanced rules”, more rules for gods, magic, heroes, loot, more terrain abilities, and special rules for games on specific realm. Then there’s going to be a few weeks of 40k, followed by a few weeks to wrap up the Realmgate War. The conclusion will take the form of an actual, factual summer campaign, as the forces of order launch an assault on the forces of chaos undecided on their home turf, all while death and destruction go around making sure everyone’s having a bad day. Then a few months later the cycle starts again. There’s going to be a few weeks of breathing time, setting up the campaigns, introducing characters, factions, and whatnot, followed by an expansion book that’ll expand on the rules and let people play their own mini campaigns, followed then a big conclusion with plenty of heroic deaths and things going south for everyone.”

So, basically exactly what others have said. The Age of Sigmar starter set is apparently – just that. It’s a starter set with super streamlined rules and missions. It’s not meant for organized play, but for gettin your feet wet with the new miniatures, game mechanics and setting. The actual “organized play” rules are described as an “codex sized” addon with all the structures and detail that players will need to make balanced large forces.

But note that the book is described as an addon/supplement to Age of Sigmar and that the rules will build upon the existing 4-page rules. So even if/when the BrB arrives, it will be Age of Sigmar in nature, not WFB 8th. It’s time to start to let that system go. It is slipping beneath the waves after 33 years of service.

~Have at it.
