These are interesting stats indeed. Further to this shared information, I'd be curious to know what the percentage of adults engage in play with strangers. I am also wondering about the context of "friends". Are these people they know outside of gaming, or are these friendships that have developed in the online world.
This is an opportunity for individuals, especially parents, to have conversations with their children about healthy gaming and tech use. When adults set a healthy example for children, children learn by example and by doing. As a result, children will learn healthy strategies for safer play.
