I do agree with the multiplayer bit. CoD, Fortnite, etc are there.Well yes that's right and that's as far as Sony should be taking RPGs.
But I don't agree with the RPG bit. I don't think a big RPG is that far off from what Horizon is. Even God of War has a fair amount of RPG elements. Bloodborne is absolutely an RPG.
I don't think Sony has built themselves as specifically a third person action-adventure company, even though a lot of their biggest titles are that. But I think they have built themselves as a single player story company which RPGs fit into that.
They actually consider Horizon to be an action adventure RPG. Mechanically that game has more in common with Skyrim, than it has with Killzone I would say. Even though it lacks some of the RPG elements, I wouldn't say it's that far off.
