The turn-based renaissance won't last. We've recently had a few great ones like Persona, nu-Yakuza, Clair Obscur and Baldur's Gate 3, but I suspect novelty factors into their popularity. We were so entrenched in real-time systems that we neglected the playstyle and now what's old is new again. Once others hop on the bandwagon and saturate it, people
will get bored of it once again.
I'd prefer it if Square Enix doubled down on the character action gameplay from 16. It was refreshing. They didn't just regress to the older games style but attempted something completely new for the series (and did it very well, listen to
authorities on the character action genre who sang a lot of praise about it). Maybe 17 could expand on the RPG elements more and perhaps open up the world more.
If I were SE I would not just do a kneejerk pivot. Maybe for a spin-off to test the waters but that's about it.
