What is your #BestOfGDC? Now's your chance to share!

Game Developers Conference has been around for 28 years now, and it's been home to many memorable talks, from the informative to the inspirational. We want to know which past talks you consider to be the #BestOfGDC. Maybe it was Shigeru Miyamoto's 1999 GDC keynote, when he talked about the evolution of gameplay and the creation of the NES, or when Warren Spector in 2003 talked about design innovation in a risk-averse world. Perhaps more recently it was the excellent #1ReasonToBe session or the rousing Hothead Rants featuring Anna Anthropy, Chris Hecker and others at GDC 2013. Tell us what your favorite GDC sessions have been over the years (any iteration of GDC is fair game, from GDC San Francisco to GDC China), and help us compile them in a helpful post that will publish on Gamasutra and GDConf.com. Use the comments below or use Twitter or Facebook (make sure to use #BestOfGDC). If you need to jog your memory, you can visit GDC Vault, where we have nearly 600 free talks available for listening and viewing.
