I wanted to take the time to adress this issue in a slightly different way, because I feel like this discussion is getting nowhere.
When I first learnt about Cyberpunk being a RPG with a first person perspective, I wasn't as surprised as others were. I was more... interested in this approach, I wanted to see what CDPR could do with it. I was, however, surprised by the resulting backlash. So, as one does, I spent some time scrolling through the trailer's comments on YouTube, and then I came here, to read what people where saying on this topic. I wanted to know why this announcement was such a huge issue for a lot of people. The answers were pretty clear, as we can see. So, here's my take on all this.
I think the real issue here is hype. Since it's announcement trailer, people have been dreaming about Cyberpunk 2077, fantacizing about the game they all dreamed of. But the thing is, with no informations on the game itself, we all ended up building our own version of it in our minds, the version we liked the most. With only The Witcher series as a reference of what a CDPR RPG can look like, I think it's safe to say that most people, if not everyone, assumed Cyberpunk would be a third person RPG. The key word here being "assumed", because nothing was confirmed, and we knew nothing of the game. It's no surprise then to see people's reactions. Cyberpunk is now becoming a real game, and you have to face the fact that it's different from the dream you had of it. The reality of it is that, everyone could fantacize about the game at their leisure, at the end of the day, we're not making the game, the developpers are.
As far as motion sickness is concerned, it's another story. Then again, we must add a bit of context. Firstly, motion sickness is not exclusively linked to FPS and other games in first person perspective (often, but not all the time). I've had motion sickness playing a third person action game (yes it was an old game with dated graphics, but still). Secondly, motion sickness is not linked only to the point of view of a game, it also depends on the performances of a game (worst performances = bigger chance of getting sick), the field of view, the graphics quality (dated graphics are more likely to induce motion sickness), and the animations (in FPP games, weapon bobbing and/or head bobbing increase your chances of getting sick), and more surprisingly it can also depends of the temperature of the room you're in (it may not induce motion sickness, but a wamer environment can worsen the feeling), and how well your gaming environment is lit. Yes, motion sickness is bad, I've had it a few times, on a TPP game as I wrote earlier, but also on many FPP games. It was never systematic, as I've completed FPP games without getting sick once, with some other games, I've been sick a few times, but not always. It really depends on many different things, not only the perspective of the game. You can also avoid motion sickness in many ways, having short gaming sessions is one, with pauses to rest every now and then, and never trying to tough your way through the nausea, trust me, it only gets worse.
My last point regards people disliking FPS, and games in FPP altogether. We all have different tastes, as far as I'm concerned, FPS games were never my favorites, I've played a bunch of them, some are great, some not so great. Would I play a TPP game over a FPP one ? Yes of course. Would I want Cyberpunk to be a TPP rather than a FPP game? No, I trust CDPR to do what's in the game's best interest. If they took this decision (probably knowing it will upset a lot of people), it's because the really thought about it. And look at it this way: Cyberpunk might be the game that will change your mind on FPP games !
In the end, I can understand why people are upset, but we're in no position to demand anything from CDPR. Yes the game might not be what you expected or what you wanted, but every last one of us is responsible for their own expectations, because before this E3, we knew nothing about the game. You wanted to play Cyberpunk, because it was Cyberpunk, and because it was by CDPR. Maybe all along, you wanted to play this game, not knowing that it might not be the kind of game you usually love.
