Knight Online is an MMORPG developed by MGame Corporation. The original game is hosted by MGame in Korea and requires players to enter their Korean resident registration numbers to register. There are three other official versions: Knight Online Xross (usually called "JPKO") is hosted in Japan, while Knight Online World (usually called "USKO") is hosted in the U.S.A, and Knight Online Europe (usually called "EUKO") . All of these versions accept registration from any location.Knight Online is officially free-to-play (although to connect to the utmost of the servers during prime time, paid premium is required), but there are some features that must be paid for. In addition, there is an in-game Powerup Shop or Store which contains various items that one can purchase such as premium packages. Paid services include exclusive items and Premiums which are a limited-time subscription providing many benefits. The player controls a virtual character. After connecting to a server for the first time, players must take sides, choosing either El Morad or Karus. The two nations are equivalent but have different appearance. Once the nation is decided, it's a difficult and expensive process to switch nations. To create a character , the player must choose (depending on the nation) a race, from Barbarian, male/female El Moradian, and the four Tuarek races that inhabit Karus. Following that, a class must be selected for the character along with a few appearance options. Finally the character is named and given its first 10 Stat Points. Knight Online allows players to fight against each other in various zones.
