I would die without an invert option.

I never invert anywhere.
I used to have the camera inverted in Uncharted, but some later TPS's on PS3 didn't let me invert only the camera(they wanted the "aiming mode" to be inverted too), so I turned to normal.

I always have to invert Y axis for every camera control, just feels right for me

By the way, the guy that chose X axis only is crazy!

Inverters are freaks.

I invert X on some RPG's - I think WKC was the most recent one, when I push right on the analog stick, I hate when your view turns left (camera rotates right)

What kind of cousin-lover doesn't invert their y-axis?!?!?

I don't invert anything, I'm controlling a camera not driving a plane. I used to have to play ass-backwards back in the n64 days and it never became second nature.

I cannot play a game that involves a camera without inverting the Y-Axis.
I'm seen as an outcast of sorts among my friends as they all tend to have a switch stuck on the utterance of the words "How can you play like this?".
My response is somewhere along the lines of "How can you not? It's only logical."

I always invert the Y-axis. Don't ask me why... maybe it has something to do with the fact that I played a lot of flight sims when I was younger?
