RPG Maker

RPG Maker, known in Japan as RPG Tsukūru (RPGツクール, sometimes romanized as RPG Tkool), is a series of programs for the development of role-playing video games (RPGs) with story-driven elements, created by the Japanese group ASCII, succeeded by Enterbrain. The Japanese name, Tsukūru, is a pun mixing the Japanese word tsukuru (作る), means "make" or "create", with tsūru (ツール), the Japanese transcription of the English word "tool".
