A graduate student at the computer science department of Sangmyung University in Seoul has earned the country's first doctorate in gaming.

Yoon Hyung-seop received a doctorate with his dissertation on massively multi-player online roleplaying games.

He said the sale of games generally correspond to their fun and popularity in his analysis of the games World of Warcraft, Lineage II and AION.

Yoon said he wants to contribute to the domestic game industry by applying his research to certain fields.
