Subcription based MMOs get a lot of the western gaming press, but that is not the dominant business model world wide. There are a host of free MMOs that support themselves through a variety of alternative business models: item malls, microtransactions, Real Money Trade (RMT), virtual asset sales (VAS), and paid expansions are just a few such models.
These MMOs are also some of the most popular online games around, and many have as much or more content and gameplay variety as the subscription based games.
