Are you sure about that ? I don’t know that much about these kind of dynamics because I am not a soulless capitalist ghoul, but I remember reading that Kotick actually did that kind of stuff mostly by himself and was quite good at it (which did translate into more money being made, which probably kept investors happy and cemented his position)
I keep joking that we should make video games mandatory for millionaires when this subject comes up but I legit think that playing some grindy game or management games would make this type of people less greedy to some degree, because at their core they appeal to our seemingly primal urge of always hoarding more resources.
