This inspriring lecture details the surprising skill that separates good designers from great ones, using examples from games new and old. Game designers need dozens of different skills, but one of them is far more important than the others, because it underlies everything else that a designer must do. Everything from fine arts to theme parks, from Michaelangelo to Mickey Mouse, illustrate how this skill can be used on your game, your team, your audience, your client, and most importantly, on yourself. This talk is designed to help you to re-evaluate and improve everything you do as a designer.
