3.5e didn't have feats that granted named attacks that were strictly superior to the basic attack. That's a 4e thing as far as I can tell.
What feats were those? Because if they existed at all I can't think of any.
4e basic attacks were a
very specific thing - with specific uses.
Meanwhile 3.5 had feats that replaced your basic attack with something better like Manyshot and Whirlwind Attack. Pathfinder doubled down with Vital Strike which took your iterative attacks and replaced them with a single more powerful attack. Pathfinder 2e doing this through a feat is entirely down that path - and through feats like Shield Slam.
The point is that PF2 wasn't made in a vacuum. 4e and 5e both were around to influence it. This stuff about immediate successor requires the idea that the game was made in a vacuum which is utterly nonsense.
Apocalypse World was around to influence it. Fate was around to influence it. Dungeon Crawl Classics was around to influence it. Yet I don't see the claims of ancestry from those. Just because other things exist doesn't mean that they were paid any more than subconscious attention to.
If they had made something similar to PF1 maybe. Did they accomplish that?
They made an explicit successor game to Pathfinder 1 using a whole lot of Pathfinder 1 design assumptions and that tried to build on what they were doing with Pathfinder 1.
Common ancestor is a evolution / genetic term. There was no common ancestor or evolution here - at least not in that sense. You agreed just a post ago but have came full circle back to the idea.
I disagreed with your assertion about genetics. As I said evolution as a word predates Mendel by 200 years.
Pathfinder was a lightly tweaked version of D&D 3.5 - any attempt to say that Pathfinder isn't directly descended from D&D 3.5 is risible.
Pathfinder 2e is an explicit sequel to Pathfinder 1e.
Already answered: 4e named powers = PF2 named attack feats
Can you give examples please? And can you then tell me how they differ from Pathfinder 1's
Vital Strike - a core feat which replaces your iterative attacks with one bigger attack. And that is fairly heavily used in the game.
I mean it fell under the 4e banner - but it was a different game and IMO helped contribute to the downfall of 4e by changing direction too much. The Essentials direction was one I disliked for 4e (and many others) - even though I liked 4e quite a bit - and at the time gave it credit for solving alot of my 3.5e issues.
I found Essentials was a really good set of splatbooks for 4e and there wasn't too much more that could be produced in the current direction.
And I have never so far as I am aware said I didn't make a hypothesis - which was then disproved by someone else. A disproven hypothesis is disproven. And something presented as a hypothesis is explicitly something I am uncertain about.
