"It's been about five years since World of Warcraft ascended to the throne. They faced early competition from the likes of Lineage 2, Guild Wars, and Everquest 2, but nothing could stop Blizzard's behemoth. Nowadays, there are many who say that there's only room for one subscription-based MMO on the market. They may be right. Other games have found success by exploring alternative payment models (such as Turbine's new item mall), but every other game that has tried to go toe to toe with World of Warcraft has failed. The list is getting longer all the time. All Points Bulletin, Warhammer: Age of Reckoning, Star Trek Online, Champions Online, Everquest 2, Aion, and the list goes on."
