Random internet comment: in my mind there are three cooperative/adversarial games that drove all of human civilization: trading/commerce, clanning/war, and prey/predator. Each of these requires vastly different strategies in different circumstances. Each scales out in a way that becomes more nuanced and complex the bigger the system. Each one, and various ones in combinations drive out other complex, emergent behavior like religion or language. Intelligence, at least on this planet, seems to thrive in a state of stress and moderate, creative chaos. There are a lot of idealists in the world who want to build something totally peaceful where all needs are taken care of and there's very little risk. If I'm correct, this would effectively kill the species over the long run.
