Good afternoon, my child spends a lot of time on the Steam gaming platform. Should we be worried about it? What are the pros and cons of Steam.

Good afternoon, my wife and I learned about Steam thanks to my son. One time he asked us to take him to meet some guys he didn't know but wanted to meet. We of course asked and he told us. The guys he plays with on Steam are organizing a meeting and he wants to get there. And after that we also went to the steam customer service and found out that it is better for children to use a nickname when registering. Since it's common in this environment to communicate with strangers.
