This article dealt with some legal issues mainly related to a Real Money Trading (RMT) in web-board games in Korea. For clarifying in detail, this paper showed lots of real case found in U.S. and China. These case studies was to reach a common principle, that is, “RMT is everywhere in the real world.” And then, this article tried to examine and evaluate whether a RMT in web-board games has an intrinsic characteristic of gambling in terms of the legal questions. In this part, this study leads to the conclusion that a RMT in web-board games does not meet the legal concept of “Chance” and “Prize.” Furthermore, it is not reasonable that providers of web-board games take legal responsibility for not only a RMT that is not controlled and caused by them but also quasi-gambling experience by the RMT. This analysis is supported by some cases ruled by Supreme Court in Korea. Nevertheless, a RMT in real world is still considered as illegality of providers of web-board games by the Korean government. And more, in recent, the government gets to apply more strict regulation to most kinds of game. This is not common and proper regulatory system in national service areas as well as the WTO and/or FTA systems.
