PhD Economist here (but not a game theorist): Game Theory is really fucking hard. In many ways the choice of what is studied by theorists and how it is framed is dominated by what we can even make tractable with our current knowledge. Very few people do full time game theory research, most of us only suffer through one or two courses on game theory and mechanism design in first or second year.
