I personally am most interested in becoming a concept artist or a character artist, things that do not relate to art are all relatively the same amount of uninteresting and mundane to me. However, the worst job would probably be programming the door or creating enemy ai and interactions with the door, as the other roles I could learn to do, but  not ones that involve programming. At the very best I would feel insufficient and inferior among my peers, especially if I was on a team of programmers.

I think the effects artist and character artist sound the most unnecessary in this situation, simply because their fields are more specific and do not always involve interacting with every in game object. PR manager sounds very easy to me, mainly because I use social media, especially twitter, and tweets like the one in the example are a dime a dozen. The only real issue occurs if there is a controversy. I think I could easily make it as a PR manager if I needed too.
