Micro Grassroots Social Media

I saw this yesterday and thought it was cool. Its basically a tiny 50 person social media network modelled on video games where you customize your home and can visit each other. I cant help but imagine a world where there are 100 such apps out there, open sourced (possibly federated?), and they replace discord for friend and family groups

Thoughts on the concept?
