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.
Maybe I’m doing it wrong or I’m just too shy to socialize with strangers in these games, but as someone who has fond memories of my favorite TF2/killing floor community servers, I feel like there is basically no sense of community in these games now that matchmaking is king and private hosting is a thing of the past
