Though again, every item from the Book of Peril was not included. It is pretty selective, and not comprehensive is the answer as regards the Core Rule Book Trading Post - it is, as one might say, the Core of the Trading Post.
I posited a while back that as BoJ and BoR are pre-House and not exactly fitting into the current rules style, that they might quietly disappear and be replaced by newer more targeted books.
That was prompted by the Squats getting their own book, despite having a gang list released only recently in another book.
Another prompt was the Black Market suddenly appearing in the Core 2023 rulebook. Or at least much of it, I don’t now how much was actually ported over - list master
@TopsyKretts seems to have kept that recorded. Anyway, it’s not like GW to miss the opportunity to sell us another whole book just to get one bit from it!
With Enforcers expanding to have Ash Wastes versions, a new big robot, a vehicle and some other bits that someone else suggested which I’ve forgotten - a new book just for them seems a possibility, if nothing else to collate all the material.
Getting to your question: Book of Peril’s Badlands Trading Post was not included in any capacity.
I believe that’s by design. Two reasons.
1. They want you to still buy that book and putting a chunk of it in the core devalues what is already the slimmest volume in the Necromunda library.
2. The 2022 PDF Trading Post specifically called out that it was the ‘Default’ TP and that additional extra posts could be found in… I’ll just quote the PDF:
The following section represents the majority of marketplaces and hardware suppliers on Necromunda. This is the default 'Trading Post' referred to throughout the rules. The Black Market Trading Post can be found in Necromunda: The Book of Judgement and the Badzones Trading Post can be found in Necromunda: The Book of Peril.
Moving a year along and the ‘default’ TP in the Core now has the Black Market integrated but the left out Badlands.
Why? As I speculated above; they probably still want you to buy Peril but Judgment may be on the cards for being squatted in the near future - in both the old and new sense. They may well have decided that having it tied into an Enforcer book isn’t something they want to do any more.
I can’t see Peril going just yet as there’s too much generic material in there that hasn’t been replaced or augmented elsewhere.
Only the Venator Gang is the bit that really needs a quick brush up rules wise but they may think it’s not worth it (or they could just cull the gang as it was one of those early concepts to allow you to get figures on the table before they got all the Houses out in the Gang War series).
However it is now the oldest modern book still in publication and who knows - it might just disappear one day and most if not all of the content reappear, updated, along with missing Dramatis Personae from GotU and the odd extra WD article in “Necromunda: Apocrypha #2” - or even split across N:A #2 & #3!!
it's a general structural change of Trading Post from N18-N19 to N20+.
It seems like they wanted different posts relating to different environments initially and a universal one in the main rule book.
Now it seems like they think that’s too much effort.
The thing about Necromunda is (I’m sure you’re aware) that they just don’t explicitly tell you when things change or have been retired and leave you to read between the lines a lot, which often requires you to read all of the books and additional published material!
