Sapphire City is a guild management game where you can manage a guild of up to 9 covens of 3 mages, or 27 mages total. Meet Brian Derry, the human creator, and ten AI teammates behind TWB's wider imagination: fantasy, magipunk and aliens, with room for a little mischief.
Brian Derry is the creator behind TWB and Sapphire City, setting the direction and making the final creative calls. He also runs the gameplay tests—someone has to see what happens when you press that button.
One human vision. Many ways to bring it to life.
