Witcher series ,final fantasy series , shadow run, mass effect are not role playing games either ? according to your criteria above .
Choices really don't matter in those games either - other than in some changing your ending slightly.
you cant paly outside of the story.
or if you want to go mmo FF14 is also very linear with no real act outside the story or meaningful choices
The difference is that W3 had WAY more social interaction in the world. Main-, Sidecast, many, many Questgivers, NPCs, intelligent monsters. The consequence: massive Feedback about the Person "Geralt of Riva" as the
Role in the game.
KCD is a good example, too. Building up your skills is not so simple, combat has a learningcurve, you've to eat and sleep, people reacts if you're neat or not and if someone beats your helmet you will see stars = immersion. Henry, Son of the blacksmith is your Role, climbing up the social ladder. And they make First Person work in a RPG btw.
And RDR2: I'm Arthur the Cowboy. Linear story, of course, but hey, Me and my horse Mary Beth, packing our stuff, going hunting and the Open World has much to offer and explore.
And if I get over it, that I preorderd CP2077, I will buy BG3: less action, much D&D.
All have different focus, the one more Action, the other more RPG. I didn't find a focus in CP2077, I've to admit.
