IGN has word from a MineCon presentation from Mojang, on Scrolls, their upcoming card-style strategy game. They outline what they did and did not explain about the persistent aspect of the game: "In the same presentation Mojang's Jakob Porser stated that Scrolls would require players to be online to play. The demo shown allowed him to face off against an A.I., and it isn't known if a connection will be required at all times whether or not you're playing against an A.I. opponent."
