I honestly couldn't tell you what you're expecting from Ragnarok. It was pretty much stated that it's going to be like the last game, but with more polish and improved combat, verticality, some new mechanics, and better boss and enemy variety.God of War: Ragnarok was just the most profound 'eh' I've experienced in recent years. God, Sony first-party games have really been leaving me cold the last 4 years or so.
As for the rest of Sony's first party, it's not too different from what happened back in the PS3 era. Where they're stuck in one genre/loop/rut and keep going on until everyone gets sick and tired of it. I straight up admit that I only care about a few of Sony's recent first party titles. I said it before, but Sony's problem is that they got older IPs, but they either don't know how, nor want to use them, because of arbitrary reasons or thinking they won't make all the money in the world.
