Level designer and artistic director. Really great games have a really compelling atmosphere, so I would use what I learnt studying Architecture to make the 3d environments really believable and interesting.

Lead game designer or producer. Everyhting else seems boring in the long run, especially if someone else dictates what everything has to look like (if I was say a grafix artist).

My greatest hobby is drawing, so i want to be a game designer :)

I'm sure there will be many people want to be designer or producer.
No one want to be a music composer?
A great game needs some pieces of gorgeous music,right?

^ I forgot music. I would love to compose the music for Elder Scrolls V.

I am sure there will be people composing music for the game industry.  There are even television and movie composers that compose video game music.  Game designer is a very desirable job for many gamers because they are the ones that come up with the gameplay, setting, story, etc. of the game.

CFO. Working for good money, and playing games when I'm in the mood for them. Though I'd more likely go yachting, probably xD

Game Designer for sure, I've already expressed many of my crazy ideas, at least one will take off and become a hit.

same here ^___^

Iwata's job.

Or at least Kotick's.
