Realm-wide pandemic hits World of Warcraft.  Whole city populations spontaneously die.  A future case-study in MMO pandemic control.  Hacker, anomaly, or has Blizzard’s massive server farm gained consciousness and turned against its account owners?  Blizz has all realms down trying to contain the anomaly.

2013 Update.  A group of german players had figured out how to turn the game mechanics on itself.  It’s a fascinating topic for the future though, as we’re growing more and more dependent on technology to communicate.  In this case, WoW has a reset that never allows for  a ‘game over’ scenario, but what if the game mechanics gave your avatar a limited lifespan?  How many players would be in an uproar when their time investment into a ‘toon’ suddenly and randomly ended via another player’s hack?
