I agree with this, I have friends that don't like RPGs but will play Skyrim, etc. It's not the fact that more genres are using first person that bothers me, it's that fact that people don't understand that (just maybe) they like rpgs or some other genre.
Then again a lot of gamers are mindless (sadly) and just want eye candy in the FPS perspective (I have one friend specifically like this.) Don't think that playing Skryim is going to = playing other RPGs any time soon. My friend openly admits that he refuses to play 2D games, RPGs, Strategy, etc. All because it has to be 3D, full of eyecandy and first person (for the most part, he does play the occasional 3rd person game like MGS4, but I bet he shoots everyone instead of sneaking...)
