"Set out on a grand adventure in this turn-based retro style pixel-art RPG, inspired by the great titles of the 90's, where players take on the roles of in-game players taking on the roles of their characters in a traditional pen and paper RPG session.

Players are able to control both the playing characters AND the dungeon master, and they choose which battles to fight. Put together a bunch of monsters to make for a challenging fight, your efforts will be equally rewarded!
"

Knights of Pen and Paper looks really interesting. It boasts launch support on Windows, Mac, Linux, Android and iOS which is pretty awesome. Having someone play AS the Dungeon Master that facilitates the game sounds very cool. I would be very interested in getting people together to play this online after it drops if its fun.
