Digital games have proliferated in the last decade beyond anyone’s imagination. The global explosion of console, desktop and mobile games, however, makes it easy to forget the significant differences in game economies between the different geographies. The economies and incentives of Korean games and the resulting play style differ from those of Chinese games. The latter are different from Japanese games and they all differ from the incentives, trading and purchase patterns of American games. As world-renowned game designer and CEO of Machine Zone Gabriel Leydon points out, the best game designers in the world know how to define, create and enable an economy that is not just suited for gameplay, but for the culture and geography in which it is played.
