No other role playing game has been as definitive to video game/nerd culture as the World of Warcraft. The MMORPG is the game by which every joke in pop culture about game playing geeks wielding swords and using magic is based on. Undoubtedly, the most recognizable role player out there, the WoW franchise has been able to survive through some of the worst conditions imaginable. Everything from hacked customer accounts to people claiming the game caused them to cheat on their partners. As wacky as the stories get, you can bet the moderators of WoW will have another one to beat it.
