Following description is directly from the the developer's site:
Ren'Py is a visual novel engine – used by thousands of creators from around the world – that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.
Ren'Py is open source and free for commercial use.
Why this package should be included in repository: Ren'Py is free, widely used and powerful tool for creating visual novels. While there are few alternatives for creating visual novels, some of them commercial, Ren'Py is generally highly regarded and has been around for a long time and remains in active development. For more information, see Why Ren'Py? Also, Solus doesn't have this kind of software in its repository.
