Heh, totally unrelated to Hines, but I had this situation in office once. My supervisior, a fellow graphic designer, was constantly fighting with the marketing department. To be more accurate, actually only with one individual - The rest of the people in marketing have been pretty decent. It was actually possible to convince them of a superior design! But this 60 year old smartypants?Public relations and marketing according the Fallout wiki.
So yeah, he's the one who goes "this the current trend" to the rest of the studio and is in charge of deciding how to market the game probably. So I'd say he's very influential in how the game is going to shape up to be.
The kind of type you just can't wait till he leaves the company. When ever my supervisior had to call him, she almost always got a heart attack due to frustration. Sometimes I ask my self, why someone with no knowledge in design actually is chosen to lead the marketing of a really big company.
Some people simply can't take any kind of advice. No matter how much sense it makes. But. At the end of the day, this guy was in charge. Andy you had to satisfy him and meet his requirements.
