In 2004 it was Ken Kutaragi. In 2005 it was the Halo designers. In 2006 it was ... no one.
Yes, Time's last list of the 100 most influential people in the world broke from tradition and didn't feel the need to include anyone from the game industry. While nobodies like Nicolas Ghesquiere and Rain got coveted spots on the list, the leaders of a $12.5 billion industry got bupkis.
Luckily, you can help rectify this situation. Yes, you, as Time's person of the year, can go independently rate the nearly 200 candidates who are being considered for the 2007 list, including Nintendo's Shigeru Miyamoto. As of this posting, Miyamoto is ranked 60th, between Indra Nooyi and Albert Osterhaus (a.k.a. two people you've never heard of) with 113 votes and an average rating of 75 out of 100.
The ranking system is based on total points accrued, not the average, so more votes equals a better rank. Vote early and vote often -- it's not like you have anything better to do at work.
