First person. I honestly cannot fathom why anybody would disagree (although obviously some people will. People do like to be difficult).
I play in 3rd person 99% of the time. When I've spent literally hours creating the look and feel of my character, why would I not want to see the fruit of my labours. if I was to play in 1st person all the time then why even bother making a cool character I'll never see? I do use 1st person for looting though, it's easier to grab the right items for obvious reasons.
How is it difficult? When i weigh immersion against character design, immersion loses. I put too much effort and work into making my character look just right to spend all my time not seeing him/her. I don't need a 1st person point of view to be immersed in the game, if the writing, acting and gameplay is solid then I am just as involved in 3rd person.
I'm roleplaying a character, not myself, I don't need to see the world through my own eyes to do that.
^Yeah, I don't get how playing in 3rd-Person = being difficult.
In Morrowind, back when I had a good PC, I would download many better body and clothing mods to make my character look good, so I would often play in 3rd-Person to look at my character, who I am roleplaying as, all the time. (If I remember correctly, it didn't matter if I hit something or not--the stats took care of that, lol!) In Oblivion, however, the combat is too focused on being too precise to the point where I am forced to go into 1st player whenever I am combating anything. =( I didn't really like that, even if I love playing First-Person-Shooters. I DO go into 3rd-Person/Vanity mode to see my character from time to time.
So, you could say I use both---because I HAD to, in Oblivion, anyway.
I just want to be able to look at my character in the game-world. Otherwise, WHY would I spend HOURS altering her face, lol!
It looks like Skryim may have an "over-the shoulder" 3rd-person view for--hopefully---more accurate 3rd-person combat. It'll be like playing RE 4/5 or Infamous or Uncharted 2, which are games I also liked. =)
