The 60-second version of The Legend of Zelda: Spirit Tracks' television commercial displays in more vivid detail why you should probably put down the DS and sleep once in awhile.
The 30-second version was nice, but I love the little details Nintendo threw in for the extended cut of the commercial. The passenger paying the panhandler in rupees; the Hyrule crest on the brass of the train fittings; the subway lights becoming torches; all hallucinations I've had at some point in the past 15 years.
I've heard good things about sleep.
