OK, got you. Thanks for the link. I agree with almost all you say, other than that third person view is generally a better fit for an RPG. As many RPGs focus on you as the player character (as opposed to a set in stone super hero or licensed character, such as the Witcher) I think first person is equally good and often better (Skyrim/Fallout for e.g.).
I do think that the game could be made fully first person, using as you say tricks and re-designs for the important story elements. Sure this is much harder for the studio (as otherwise it’s pure movie stuff, without limitations), but again as you say this is the advantage of games over films - Immersion and first hand interactivity as opposed to the voyeuristic hands-off approach.
IMO it would be worth the extra effort if possible to set the entire experience in first person. It’s a stretch goal I would certainly increase my pledge for (unlike playable miller’s daughter + big name actors for e.g…).
