So I browsing the web recently when I found this. http://www.valvesoftware.com/company/publications.html Most of the presentations seem to be slides without much on them. I guess that most of the presentation was verbal rather than reading off of slides. However, I found a particularly interesting one where the person uploaded their speech notes along with the slides... http://www.valvesoftware.com/publications/2012/GDC2012_Ruskin_Elan_DynamicDialog.pdf I thought it was fascinating to read about how Valve creates such things... The guy from Valve mentions Fallout, Skyrim and some other games as well.... What do you guys think?
