The life cycles of game genres and the lessons that they teach us.
Over the years people have bemoaned the rise and fall of various gaming genres, but there has been little analysis behind the functional processes that drive this critical market systems.
Genres are a major defining factor in the creation of rich markets of avid gamers and designers ignore them at our own risk. We cannot assume that a genre will always exist, or that a genre will have competitive room for our latest title. A genre in the wane is a dangerous market where past success is no indication of future success.
Equally important is the opportunity that genres present. If we can understand how genres arise and change over time, we can tilt fate in our favor by releasing and developing new titles that hit emerging genres with the correct timing and release strategies.
