They are biased, but not politically: they are biased technically, toward models that present a simplified model of the world that can be simulated reasonably. Even more so for game designers who have to make a fun game while staying a bit realistic. Scientists use simple models because they have technical constraints. I do think that right-wing libertarians are wrong because they have a much simplified model of the world, that does not take into account all that you mention. I am as far left as we go in France but that's a recurrent leftist criticism that I keep seeing and that I think is really misguided.
