The Gamers: Dorkness Rising(2008)

All Lodge wants is for his gaming group to finish their adventure. Unfortunately, they're more interested in seducing barmaids, mooning their enemies, and setting random villagers on fire. Desperate to rein in his players, Lodge injects two newbies into the party: a non-player character controlled by Lodge, who the power gamers immediately distrust, and the rarest gamer of all -- a girl.
