Maybe next you can do a Builder spinoff where you have to go build in a remote African village. All the husbands are impotent and you have to impregnate the African wives. lol. I'm joking, but I'm not.
spinoffs, prequels, sequels - bring them on, I'm collecting ideas!
Best way to help that materialize is to add The Builder to your wishlist on Steam so that we make a splash when it releases, that will improve the resources for development even further :)
