Monetizations features are what makes us possible to earn money indefinetly from the game. This features have some developments task related with the game client but are mostly handled by backend technology and development and not directly by core game code.
They require special design and development from teams or departments not directly related to the game development like GROWTH (marketing), CORE DATA and LIVEOPS. This have to be analyzed, studied, developed and configured in accordance to the user data base (aquired after releasing the game), monetizations trends at the moment of release, anlaysis of what the competition is doing, market state and marketing costs (Common KPIs like UA, CPI, CPR, etc.).
It is not the goal of this document to enter into a lot of detail of this features as they depend a lot on the completed development of the game and the previously told conditions and departments.
