At this year's GDC, I had the opportunity to give a brief talk at the Artgame Sessions, organized by John Sharp and Daniel Benmergui. That session, along with many others, can now be streamed for free at the GDC Vault.
I have to admit that I haven't actually watched any of the other free sessions, but Robert Zubek's "Engineering Scalable Social Games" sounds interesting in a know-your-enemy kind of way.
I can definitely recommend the Artgame Sessions, if nothing else: Iriquois Pliskin gave a great talk about Braid, Jason Rohrer defended Terry Cavanagh's Judith, and Frank Lantz compared Messhof to Sid Vicious. Your enjoyment of my bit about Far Cry 2 is highly dependent on how sick you are of hearing me talk about Far Cry 2 (also, spoilers for Far Cry 2.)
