I was actually planning a similar future project somewhere (not sure where yet coz its still all in my head). I wanted to recapture a small village or small town feel like what I started in Ynys Affallon in Alpha/Beta. Couple of the people I started the project with back then said they missed that feel there. But, I was a little dis illusioned with the current dire lack of interactable furniture and decorations after seeing what Portal Knights has. So I decided to pull down my present builds and retire into a storage cube waiting for QOL improvements and more decorations and furniture to come into game first.
I was actually toying with the idea of making houses in a unified style but different designs, with a strict set of colors and materials, and then advertising after that for people to come “buy” up a completed house with a mutually agreed rule (unenforceable since I can’t control another player’s action) that they need to maintain the fascade to upkeep the reason they wanted to come here for in the first place. Everything that can’t be seen from the outside is up to them to remodel as they see fit. Obviously, they can redo any gardens if there was any.
