A social casual game that's not a giant hairball of money-grabbing dark patterns, that's a tall order.

You might find something here, I've found some pretty good games on Android at least: https://nobsgames.stavros.io/ios/?s=reviews&page=1

Would Among Us be a possibility, or some other Mafia game? Town of Salem might fit the bill: https://store.steampowered.com/app/334230/Town_of_Salem/

I'm going to follow this thread, please comment if and when you find something, I'd really like to know what does and doesn't work for situations like this.
