I love games--I enjoy playing them and watching them. However, games have become a powerful metaphor in our society that has helped to erode the complexity of our moral thinking. The moral conditions of life are too nuanced to allow game metaphors to dominate our social and political thinking. Please see the article, "Business is Not A Game" https://link.springer.com/article/10.1007/s10551-008-9859-0 or the chapter, "Politics is Not A Game" https://works.bepress.com/maurice_hamington/43/

Yes, games have been a human passtime all over the world. They are universal. But as Maurice points out, games and game theory may be abused. By abusive people. And by abusive governments, corporations, even those entities whose aims are ecclesiastical in content. Neither is this all that recent. The best example of man's inhumanity to man came during the darker age of civilization. The Churchmen administered all sorts of torturers to those who defied their authority and chose free-thinking or some other blasphemous course. Reprogramming had early origins---and, it was not merely psychological. Anyone who free-thinks a bit may want to examine some accounts of these early efforts at corrective socialization. Titles coming to mind include: Strange Gods by Susan jacoby and, of course, The Better Angels of Our Nature, Pinker's tome on the notion of decreasing violence.

I used to play Bridge and Euchre. Over the years, I withdrew from participation. Some players got way too obsessive, bordering on violent: when it ceases to be a game, it is time to find other passtimes.
Now, I read and write philosophy. One is cautious, however. As one of PT's posts has noted, there are trolls and bullies out here. Even philosophy is fair game ( play-on-words, obviously intentional...).
