Never heard about this one, but there's another post about a design class in Animal Crossing, maybe you two can exchange some ideas.
It's amazing and I'd propose the entirety of the innovative personalities of DN to give it a shot on the off chance that they have a great deal of time as I do https://ifacetimeapp.com/
It's an open world game where it has no boundaries or rules. Everything is created by the players who can draw and design specific blocks. It's incredible and I'd suggest all of the creative minds of DN to give it a shot if they have a lot of time like I do.
