KNight-Blade: Howling of Kerberos was one of seven sample games released in the Japanese version of RPG Maker XP. Unlike most sample games, KNight-Blade: Howling of Kerberos has an actual plot (Yay!) and completely customized graphics, which have now been taken time and time again for use in other fan games, etc.
At only 18 MB download, KNight-Blade: Howling of Kerberos sports quite a bit of customized graphics and, as many would believe, is not medievial. In fact, it takes place as a sequel to a RPG Maker 95 game about the same characters in the same high-tech setting.
