Mikhail Fiadotau, a lecturer in video game studies at Tallinn University, identified three primary distinctions between the established dōjin culture and the Western idea of indie games. From a conceptual view, indie games generally promote independence and novelty in thought, while dōjin games tend to be ideas shared by a common group of people and tend to not veer from established concepts (such as strong favoritism towards the well-established RPG genre). From a genealogical standpoint, the nature of dōjin dates back as far as the 19th century, while the indie phenomena is relatively new. Finally, only until recently, dōjin games tended to only be talked about in the same circles as other dōjin culture (fan artwork and writing) and rarely mixed with commercial productions, whereas indie games have shared the same stage with AAA games.
