Well in Skyrim I'm playing mostly in 3rd POV, while in Oblivion I liked playing 1st, dunno why but 1st POV in Skyrim seems too close to my face and I can't see most of the area...
It's because the default FOV in Skyrim is atrociously low. If you're on PC, you can change it via a console command - makes it possible to enjoy 1st person view.
I'm not sure if I should admit it publicly, but I always played TES in 3rd person view. Only in Skyrim I changed it to 1st person because I'm playing an archer. I think I'll stick with 1st person for my other playthroughs too, though.
