If the culture at Valve is one where everyone has self-determination, anyone trying to "dominate" others would quickly start to be seen as a dick, would stop being able to find collaborators, would stop being able to get much done, and would eventually be weeded out. Anecdotally, I dislike telling people under me what to do, let alone "dominating" them. I much prefer working with people who are self-directed individual contributors. I would not want to hire anyone that I thought matched your description, and if I found out that they did, I would fire them when I saw any clear evidence of it.
