I personally have known several people. They are not narcissists. They are literally 100x talent. One of them built out a half dozen hit games, doing all the art and programming for one employer which represented half the companies profit.
Then he left, started a 30 person company, got frustrated, quit and built another game entirely from scratch doing all the art direction and sold millions then retired.

One person.
