I'll be playing in FPP for sure, driving included (I mean I'll be drive in FPP as well). I was kind of happy when they officially said it would be in first person. Sometimes you need to force a situation for everyone in order to push a certain kind of sensation you wanna give with the world etc, plus It makes a better look at the details and works good for immersion. If done PROPERLY. I often wished the witcher 3 to be in first person to appreciate the interiors, the details, and deliver me from that awful combat and Geralt's ugly model an aminations. (I had to install a mod to have it barely playable).
FPP is a design/artistic choice BUT:
1-Saves time because you don't have to make a good animated playable character. Because you won't see it and most studios use two different models for first person and third person. Actually in FPP there's no model in most cases, you're just an invisible entity moving around with a floatin gun, and maybe arms.
2-Makes the overall experience stiff if you don't actually animate the only model you use in a detailed way. If the point of view sticks to the eyes and you animate the head it might be a problem, it would suffice to keep the wobbling to a minimum, but at least animate combat animations and some not so problematic for movement enforced wobbling causing sickness. GTA and RDR first persons deal with many issues in clever ways.
When I saw the shadow of V on the container in the shooting footage of NCW, i was "Ohhh my...here we go". The character model was stiff as an iceberg as you could see from it's shadow, and looked like a model straight from CS mod. My bet is that clunckiness is partially given by the fact that they are using the same character model both for first person and as an entity in the world (like arma3 does it). That's why it feels cluncky.
Video for reference at the point I was describing. Check out his shadow and when it's projected in the room, don't look at the gun or the enemies, just focus on the shadow. That's where the problem lies. (if the bookmarked minute doesn't work for you jump to 17:55 and go from there)
