As of 2008, the market for MMORPGs has Blizzard Entertainment's World of Warcraft dominating as the largest MMORPG,[21] alongside other titles such as Final Fantasy XIV and Guild Wars 2, though an additional market exists for free-to-play MMORPGs, which are supported by advertising and purchases of in-game items. This free-to-play model is particularly common in South Korea such as MapleStory, Rohan: Blood Feud, and Atlantica Online. Also, there are some free-to-play games, such as RuneScape and Tibia, where the game is free, but one would have to pay monthly to play the game with more features.
