Big Eyes
After "Big Eyes, Small Mouth", Guardians of Order would go on to achieve significant success with the "Sailor Moon Role-playing Game and Resource Book". The game was built on "Big Eyes, Small Mouth" but featured an extensive reference to the "Sailor Moon" universe. Guardians of Order acquired licenses and published "Big Eyes, Small Mouth"-based RPGs for a number of other anime series including "Dominion", "Demon City Shinjuku", and "Tenchi Muyo!". After "El Hazard", the last such game, the company's strategy with licensed anime series changed and it began issuing "Ultimate Fan Guides" which served the same purpose while avoiding the need to reprint the same "BESM"-based mechanics. All of these books included game statistics for characters in the series as well as extensive episode guides and character summaries.
