Generally I worry about online gaming.

I played a lot of Titanfall back in the day and had a lot of reservations about talking with other people's kids. Nothing really bad happened, and I had a lot of fun, but it was creepy.

I kinda enjoy that the matchmaker rooms in Beat Saber only allow you to emote with large body gestures and not say anything or even make hand gestures. I enjoy acting like a cartoon character to honor and recognize the other players (like choosing the song that I really hate because another player has asked for it five times in a row) and not getting involved in the mean bullshit you get in games like League of Legends. (It's fun to be in a private room with 2 or more players too where you can chat but then you are talking with people you picked which in my case are nice people)

My son and his friend created a new game called "the kick game" inside a certain online game where the real game was to trick the other players into kicking out other players that they didn't like or wanted to bully -- frequently the victims didn't understand the rules of this game at all. On Roblox they would find racist games where you cut down thousands of Zulu, just awful stuff.

Not to say I haven't had a good time with serious League players who communicate on Discord and have a positive team but I think communication features and UGC are often a disaster in games.
