OK, so let me get this right....
1st person view is less immersive because you can`t see your peripheral vision, even though you could just turn your mouse and stick quickly to make up for that, but it would be ok if we had a surround visual system...
So that`s why you stay with 3rd person which has you 10 feet above and behind yourself and that`s NOT more unimmersive than having a view which is more true to looking through your own eyes?
Now tell me the REAL reason you perfer 3rd person.
I`ve had some people say they play in 3rd person because 1st person is too scary, especially in dungeons where something can actually surprise you.
1st person is more realistic and immersive than 3rd, no matter what excuses people cook up to try and pretend 3rd is better.
I never said 3rd person was immersive. The truth is, with current technology, there really isn't any way to feel like you're really there. I guess if you try really hard...
I always used to play Everquest in 1st person too, mainly because the original game's non-first person cameras were pretty much useless for actual gameplay. Eventually, they included a "directly behind" camera angle that allowed you to see around you, yet still be focused in the exact same direction as your character. I still stuck to 1st person for a long time, because by then, I was so used to it. Eventually, after playing several other games, each of which had a much better 3rd person camera, I got to where I much preferred 3rd person, and have used that much more than 1st. It hasn't cost me any immersiveness.
I began playing RPGs with D&D back in the 70s. Imersiveness then came from your own imagination, with absolutely NO help from the computer. So to me, that's STILL the main source of immersiveness. I feel like I'm actually the character not because of what my eyes see, but what my mind sees. It's just as easy (actually far easier) to imagine that I am the hero fighting the dragon when playing a computer game with great graphics as it was to imagine the same thing when my entire vision of the dragon was the description given by the dungeon master, as well as my own preconceptions of what a dragon should look like.
As someone else mentioned, turning the mouse to see your periphery is like turning your whole body. Your character's head doesn't work independently from his feet, it seems, not to mention his eyeballs. I can keep facing the screen on my laptop to type this message as my eyeballs can pan left to look at my work PC, to see if I've gotten any new emails. Not only does my body not have to move, I don't even have to turn my head. The character on the screen doesn't have this capability, and it's really painfully obvious. Perhaps some people have the ability to overlook such a glaring problem, but I can't. That issue actually ruins immersiveness for me.
On the other hand, 3rd person doesn't add to the immersiveness, either. But it does have other advantages- it allows me to watch the beautiful animations that gamesas went to so much trouble to create, for one. It also allows me to get a much better feel of the situation in combat. I can better judge how close I actually am to the Draugr I'm fighting. And I know what you're getting at- you think I do it just because it allows me to "see" behind me. You can believe what you want, but I personally don't gain much advantage from that. Maybe it's just me, but I can really only focus hard on one thing at a time, and while it may register that there is another mob behind me, my brain can't really mutli-task well enough to do anything about it, because it's focused on the fight in front of me. In other words, I may be aware there is another mob beating on me, but putting that knowledge to use is somewhat beyond my capability.
I do find playing Skyrim in 3rd person more challenging than other games, mostly because the camera isn't directly behind the character. It's off to one side, a bit. (I wonder if a mod can fix that?) That's what makes using ranged attacks in 3rd person so difficult. I think I may start trying to master that as well, though. It will be a good challenge, and once I have it down, I won't have the issue with forgetting to change perspective.
