I've skimmed enough of the thread to realize that other people have already held this opinion, so at least I don't have to be
that guy, not that I mind being
that guy...
Anyway...
Nothing. Nothing breaks my immersion. The way I look at it, the definition of immersion, at least as it's being discussed here, would imply not thinking of the game as a game. If that's the correct way to look at it, nothing has ever broken my immersion because at no point as a DM or as a player have I ever stopped thinking of the game as a game.
I don't say this to be contrarian and simply post an opinion outside of the norm or what the thread is looking for, it's just the way it's always been for me. At no point even deep in a moment of role-playing have I ever stopped realizing the basic fact that D&D is a game that my friends and I are sitting around playing at a table in someone's home.
Now I don't say this to belittle anybody who has one or more aspects of the game that get under their skin and break their immersion, everybody's game is different, which is of course one of the best things about this game. If anything, reading all of the different ways so many other people have their immersion broken by different aspects of the game make me a little bit more grateful for not having the same issues. Plus, it's always interesting to read about other people's experiences, even if I don't necessarily see eye-to-eye with them.
Anyway, that's my answer to the question posed at the beginning of the thread. I'm not sure I've contributed very much, but it's the internet, so I suppose making a comment without actually contributing much to the discussion is really just par for the course.
