The Ren'Py Visual Novel Engine (or RenPy for short) is a free software game engine which facilitates the creation of visual novels. Ren'Py is a portmanteau of ren'ai (恋愛), the Japanese word for 'romantic love', a common element of games made using Ren'Py; and Python, the programming language that Ren'Py runs on.
