Games definitely have an impact on society, and I think overall it is a positive one. Games teach us how to cooperate and play on a team. They teach us the importance of working with other people. Most games you can't win just by playing by yourself. Games are good for learning.
Games only firstly impact those that play the games. If one does not participate in the games then they of course have no impact on ones life. However, of course it would be different for those that do not play games. I don't see mass discussion on people talking about an impact on society however.
