I think you are so right. Communal living situations will always attract similar types of people. They are often looking for something they can't find in everyday life, an escape, a fantasy. Games and play are a big part of this.
When I was young I lived in a commune in an old mansion for a while, (I was a true dippy hippy), and we had regular games nights, charades, fancy dress etc. It's easy to start out feeling you are part of a perfect community. It feels like a utopia, a new way of living. Then the cracks start to show and the personality clashes start. People have affairs, then break up which can destabilise a close community. . You start to get bored and annoyed by some of the people and realise that some are social misfits or mentally ill and do you really want to be there with them? and at that point you go back to reality..( Iris Murdoch's novel "The Bell" is a great novel about a fracturing commune.)
I think the earlier vlogs were lovely. The volunteers were nice, youngish people looking for adventure before they settled down in their lives. Now it feels as if every new person is on the make, clinging on to Stephanie, to launch their own business or vlog, as Stephanie hags becomes obsessed with collecting tat to appease her rich patreons. The dynamics have changed. Even otherwordly Selmar had got in on the act.
I was actually pleased to see Michael Potts Nic and their partners return to the chateau. The vlogs were getting so boring. I'm looking forward to Cat returning, (if she can with all the confusion over the amber status France has in the UK.).
