When Wizards of the Coast moved on from 3.5, a lot of people went nuts, because they thought 3.5 was the end-all-be-all for tabletop roleplaying. Paizo capitalized off of that by taking, what was basically, the 3.5 rules, tweaking them slightly, and selling it as Pathfinder. I've got 5th edition D&D, for sure. But some players still swear by Pathfinder (3.5), and I like to roll with both groups. However, Paizo is beta testing Pathfinder 2nd Edition *gasp*! After nine years of rolling out supplement after supplement for Pathfinder, they finally ran out of stuff to do with it (that would be worth the money, anyway). It's all a bunch of expanding or simplifying based on player expectations and playing to your audience and squeezing every bit of content out that you can. Genius, really. Wizards picked up the players who didn't like the math of 3.5, and Paizo ran with die-hard 3.5 fans.
...MercurySteam, you taking notes here?
Anyway, what were we talking about?
