This is kinda weird to me because I think the opposite of that. I feel like the main motivator for our society improving is competition whether it's trying to get the highest grade in your class or trying to build the most popular electronic. It keeps us on our toes and we have to constantly improve ourselves to be better than others because they are also trying to improve themselves to be better than you. As long as no plays really dirty like stabbing someone or whatnot, I feel like competition is one of the best things that happens to our society.
Also there's not a lot of point to quitting a game that ends on it's own anyway.
