>Shouldn't your goal to be to make great games?

That was an implied sub-goal. The verification criteria I gave was merely to illustrate what the concrete results of my endeavors might look like. If I said flatly "I want to make great games," then someone might reasonably respond "how do you know you're succeeding?"

>For goals like yours, politics and personality can matter as much as the work itself.

This is quite true. But Paul Graham has a great quote which I think might be applicable here: "Everyone in the sciences secretly believes that mathematicians are smarter than they are... And so there is a great temptation to work on problems you can treat formally, rather than problems that are, say, important."
