Role-Playing In An Anime World!
Big Eyes, Small Mouth is a multi-genre RPG, inspired by the dynamic characters and stories found in Japanese animation. Comedy or horror, fantasy or science-fiction... if you can imagine it, you can play it! The game rules accurately reflect the "anime atmosphere" by emphasizing role playing rather than numbers and charts. Additionally, character creation can take less than ten minutes, and is extensive enough to offer characters magic, mechs, psionics, heightened abilities, unique artifacts -- the options are nearly limitless!
Ages 12 to Adult. Requires 2 six-sided dice.
