I think you are taking some generous leaps in using “we” and saying that “we” were all content with 1E. 1E was creaking on the weight of an already refurbished chassis. There were plenty of people that were ready for something new, evidenced by so many old Pathfinder players switching to 5E and there are plenty of people that love the new 2E.
If your evidence that Pathfinder 2E is not being received well is based on the tiny minority of players/GMs that posted on the Paizo boards or the fact that 2E isn’t outselling 5E then I don’t know what to tell you. With 5E’s enormous success and brand penetration, Pathfinder 2E would have to do something spectacular or more likely, WOTC would really have to mess things up to lose the crown to Paizo.
I'd imagine it's based on comparison numbers (from such things as online RPG surveys which show that online games of PF1, at least those that I saw, still outnumber PF2 despite PF2 being the actively supported RPG with new material being brought out for it. In addition, comparison of how sales of PF2 are doing in relation to other RPGs). Still, if Paizo is all behind PF2 currently, that indicates that PF2 is doing well.
There are numbers we have no idea about (subscriptions directly from Paizo, sales on their site, etc) that could amount to a LOT more than what people are seeing otherwise. PF2 could be their best seller yet for all we know.
This sounds really interesting, although considering recent enhanced focus and sensitivity on matters of this nature I hope the book was very carefully compiled.
One of our groups members is an avid Pathfinder player and tried to convince us to switch to PF2e (they did not succeed). We've had various fallouts and returns with them over the past few years, and they constantly try to convince us to do Pathfinder campaigns. We occasionally humor them with PF1e where they DM.
I have lost much of my interest in PF as I'm not a big individual into 3e or the subsequent systems these days. HOWEVER...the mention of this book sparks my interest. This may be interesting enough for me to pick up, and I support the endeavor which spreads awareness and thought into different communities than is normal for our RPG community these days. Whether it is PF or not, this has perked my interest. It seems interesting.
One thing that MIGHT turn me off is if it is NOT primarily written by POC and more specifically those with backgrounds, or a cultural and ancestral heritage which traces back to Africa. Too often we have those of European descent dictating what other cultures should be written as, rather than refer to those from those actual cultures and backgrounds.
Many times, especially in the RPG community, these writers and creators are excluded. This would be especially heinous considering the material this source book covers.
I know it is a fantasy world, but this area of Golarion I think refers specifically to areas with a close relation to portions of our world, and as such, attention to things occurring in our world would seem tantamount to me.
With the right writers behind this, as well as editors and producers, call me EXTREMELY interested in supporting such a product. At this point I'd probably pick it off of Amazon (so, Paizo, price it accordingly to make a profit, sometimes those Amazon prices seem way to low to be making money off of them) as that is recently my go to place for many of my purchases (blame the pandemic).
