Bright Hub writes: "No single game in the history of MMOs has enjoyed the success of World of Warcraft. Record numbers of subscribers and overwhelming critical acclaim have elevated WoW to the undisputed king of the MMO world.
Unprecedented success of this nature can't help but have repercussions on the future of MMORPGs. Players who have enjoyed the many revolutionary features of World of Warcraft are unlikely to abandon it for another game that doesn't posses certain qualities they have become accustomed to.
Whether in terms of customization options, questing and leveling, instanced encounters or item transfers between characters, these aspects of World of Warcraft are inevitably here to stay, changing the way we play MMOs forever."
