Friday at GDC Austin saw the day starting with a keynote that may seem unusual to players unfamiliar with the Asian online gaming market. Nexon is a major player from the country of South Korea, boasting a handful of titles that see more users in a month than many well-known online games made here in the US. All of the company's titles, regardless of genre, have one thing in common: they're free to play, sort of. Microtransactions, the practice of paying a very small amount of money for an object or service, is what provides Nexon its revenue ... and plenty of revenue it is. Nexon America's director Min Kim gave a discussion on the realities of rolling Microtransaction-based titles out in the states, with a case study of the success of Maple Story's launch in our country.
