In the past couple of years, Corum Online has been one of the top-ranked games in the Japanese and Korean Markets. The story is a common one - the world is in danger and you've been charged with the task of saving it.
You can choose from a range of characters such as a magician, soldier, warrior, etc. and your abilities can be beefed up as you progress through the levels. Where the difference lies between this and other games of its genre is that, in that in addition to a map, you have lots of hidden dungeons to explore where enemies lurk that will raise your profile as a character. That said, there aren't a huge amount of missions to accomplish once you've raised the stature of your hero. Graphically, Corum Online is very impressive and features characters inspired by comic books, complimented by a soundtrack of unquestionable quality.
