People pass out while playing Final Fantasy XI

It seems the developers of Final Fantasy XI may have been inspired by the Southpark episode "Make Love, Not Warcraft", where the main character children put their life on hold to play World Of Warcraft. They have created a boss character, Pandemonium Warden, that takes about "a solid day" of online continuous fighting to beat. FFXI is an online massive multiplayer role playing game (MMORPG) and beating the boss is not a requirement, but an added quest of sorts. After about 18 hours of high level players battling, the boss' health level seemed to be untouched! Players from that guild said "People were passing out and getting physically ill". Other players in Asia have been reported to die after playing other games 18+ hours straight, mental and physical exhaustion were to blame. How far will people go to play games?
