On the main IGF site you can now view all of the 570 entries to this year’s Main Competition, including mobile games which are also eligible for a special mobile award. In years 2011-2007 there were 391, 306, 224, 173, and 143 entries, respectively. So yeah, a big year for the competition!
A couple weeks ago, I posted some of the new trailers I thought were cool, but TIGForums member esc has assembled a list of lists that makes it much easier to view all of the entries as well as their trailers.
Finalists in the competition will be announced in January 2012.
