Big Eyes Small Mouth is a multi-genre roleplaying game created by the now-defunct Guardians of Order. Conceived as a system to allow people to play out games in the style of anime series, it was first released at Gen Con in 1997. The name comes from a common generalization of the typical anime and manga character designs, which have proportionately large eyes and small mouths. See also Silver Age Sentinels, GOO's superhero RPG that used a similar rules system.
