In my house we have minecraft Lan parties for 8 year old girls. Minecraft is quite good for this because it's such a deep game that realtime help is very useful and the girls are not really able to research on the net, So the social aspect becomes more important to them. Also minecraft is quite cooperative anyway.

Also VR parties are sorta similar in vibe to LAN parties too. I feel this stuff is sorta alive still and it was niche in the 90s too.
