Turf War was perhaps a mistake, something they want to throw a vortex grenade at. The Special Territories was mostly copy-pasted from original Necromunda. The mechanics of Special Territories was also bad, many gangs would never even gain any of them. The rest of the campaign rules had bugs, for example advancements which was corrected in GW4 with Dominion campaign.
I'd love to see both campaigns. But would they be able to create a useful layout for it? I had to separate those things that were common to a new chapter, let's call it "Generic Campaign rules" that include things like lasting injuries, advancements, xp etc. Then I had to detail each campaign type in separate subsequent chapters. Or they duplicate the common parts for both types of campaigns into their own chapters. First of all, they have not been good with layout, so this may be too complicated for them. Secondly, duplication has proved to be disastrous in N17.
The page "HOUSE GANGS" and subchapter "GANG COMPOSITION" is not compatible with Turf War, because it does not have any limits on Champions except the usual 2 before the first game. Which means that anyone would just save all their money and buy champs after 1st game. Or they would need to make additional limitations somewhere else (not shown on the image).
