Kotaku: "Congratulations, good people of Valve Software. You make terrific video games. Tell us how it's done!
"I'm stammering because I've tried to explain to my wife how it works, and I haven't been able to," Erik Wolpaw, co-writer of Valve's Portal 2 said last week, answering a question from a moderator about Valve's game-making process. "She doesn't believe that it should work."
Wolpaw's full NYU presentation—covering Valve's methodology, Portal 2 heroine Chell's reluctance to speak, and plenty more—was recorded by the University and is scheduled to be posted online soon."
