re: floating camera with arms....
I dunno, I've never felt that way about my character in a first person game. Even the ones that don't have third-person cutscenes, or mirrors.
Yeah, I don't do that. 
(The main problem with the word is that it's vastly overused, and with all sorts of different definitions. And that much of that overuse is by people throwing "ruins my immersion!" at any feature that they don't like. Based on what I've read, it's apparently an incredibly fragile thing that breaks if you glance at it wrong, and ruins games. Makes me glad that I don't appear to suffer from it. )



Crashing every time you enter a bad map cell, on the other hand - particularly one that contains an important quest destination... not fun. But not because of any "immersion" thing, just because it interferes with playing the game.)
