I've spent a lot of time thinking about why I and many others don't, won't or can't play games in first person but it all boils down to the fact that it's a miserable experience no matter how "good" the game is.
I knew I didn't like FPSs when I started gaming but I thought it was because it was mindless shooting. When everyone kept telling me to play Mass Effect, I kept putting it off because it was a "shooter" in my mind but it turns out I really enjoy shooting in third person even though I really sucked at first, swapping my sword for an assault rifle.
When Deus Ex:HR came out, I was sure I would get over it because the game looked awesome. And it was... objectively speaking. I loved everything about the setting and the story, the stealth and the augments. But after a few days of playing, I realised that I wasn't actually enjoying myself. First of all I just felt completely disorientated being this disembodied "ghost" or just a pair of hands moving about the world but also I just felt really uncomfortable being in the "skin" of Adam Jensen. I didn't like getting shot because it felt like I was actually under attack, I didn't like the creepy polygon people looking me directly in the eye... I just hated it. I couldn't role play as Jensen because I felt like I was him and I wasn't under any illusions that I was some badass super cyber cop. It all just felt wrong. I felt too exposed and I stopped playing.
I tried to pick up a couple of FPP games since and it is always the same story. I just hate it. And as I've gotten older (only 36), I've had health problems with my inner ear and my vision that makes playing FPP games physically exhausting or vomit-inducing the few times I've tried forcing myself to give them a chance.
There are dozens of games that I would love to play but I just can't because of forced first-person such as Metro, Bioshock or Far Cry to name a few.
I wasn't really a fan of The Witcher series (didn't like Geralt at all) but I can see 3 was a good game (story/setting) made by a talented and dedicated team of devs so when I heard they'd be making a Cyberpunk game, I was interested. After seeing the trailer at E3, I was really invested, especially because of character customisation, but now that I know it is FPP-only, I know I won't be playing it.
For some people, FPP is a dealbreaker and everyone should respect and understand that. I'm not going to beg the devs to change the game for me but I won't be buying it and I understand why long term fans of CDPR are heartbroken. If one of my favourite developers suddenly started making games I couldn't play anymore, I would be devastated too.
All this talk of "giving the game a chance" or arguing which POV is more "immersive" is pointless. Most, if not all, of us have been giving FPP games a chance for years or even decades and they just don't work. So when someone next says, "I'm out", just accept it and move on instead of trying to shame people into playing a game mode they know full-well they will hate.
Those that are far more invested in the game that I am have a right to speak up about why they won't be playing, if they can be respectful while asking the devs to reconsider. Maybe CDPR underestimated how many of us can't or won't play in FPP, and maybe they'll do something about it... or maybe they won't. Trying to defend CDPR's "artistic integrity" on their behalf is ridiculous. Just move on.
