Traditional game development consists of the developer working behind closed doors on their vision. Periodically, and in very controlled circumstances, the customers can see the work in progress but that is mostly elaborate trailers, often not even showing actual game play. Most importantly the customers cannot give feedback while the game is still being developed. Co-development by being open and agile completely changes that paradigm. Customers see the game at all stages and begin playing it as soon as it is possible, providing feedback that can change the game for the better. This method requires full transparency and a very regular cadence of content delivery.
