The demo was beautiful. Also, it suggests to me that the game demoed may not be for me (which is OK, but since you asked...), no matter how attracted I may be by the setting and the world (I had no knowledge of the particular tabletop RPG before I heard about this game, but I enjoy books, films and series of this subgenre.).
I'm not strictly a Third-Person player, but I can't stand First-person for too long.
I disagree with the official line that FP is the way to go because of immersion. Most important thing, for me, is and always will be the story. That's what will drag me in. Doesn't matter if the game is in FP (or TP) if the world is not fully interactable. Now, from what we were showed, this game seems to have a decent amount of that, which is good.
And honestly, most of the time FP is actually immersion breaking. I have no idea how the world is through other people's eyes, but my eyes' lens seems to be always much wider than what games portray. It always seems to me that a chunk of the world, as I see it, is missing. I have the expectation for it to be there and it is not.
It may well be that this is too late to happen (or that, no matter how early or late, it's a final decision), but I wish the devs would reconsider and have TPP. It would change this to be a game I would have to watch some footage and maybe play a demo before buying, to a game I would pre-order as soon as that was available.
