Ancient-Red-Dragon: No it's not. Pure TBS with no RTWP whatsoever is
actually the way to do it.
Last time someone tried to make a "hybrid" RTWP/TBS game, that was Pillars of Eternity 2, which ended up having a heavily botched TBS mode which was unable to be implemented properly, because truly it had RTWP mechanics way too firmly embedded into its core structures.
I suspect all the same will probably be true of this new Pathfinder game.
In the case of Kingmaker it was actually the other way around, it's RTWP had TB mechanics too deeply embedded in it's core structure. It was an adaptation of tabletop RPG after all.
eric5h5: I would assume it's like the turn-based mode they added to Pathfinder: Kingmaker, which I do have (specifically because of that) but haven't played yet so I can't say how well it works. Gotta be better than RTWP though.
Works lightly buggy and janky, but otherwise very well and indeed "better" than RTWP.
StingingVelvet: Does this one have the kingdom management stuff? Loved the original and finished it, 150 darn hours, but could realllllly go without the kingdom management, which was largely an annoying waste of time.
Nergal01: Instead of managing a kingdom you'll be in charge of an army, as far as I know. Your alignment and the mythic path you choose will influence this part.
If I recall correctly, they promised something like HOMM with the regards of army leading.
