Slides from Elisabetta Silli's talk in the GDC Europe 2010 panel about level design. Movie content can be found on: http://publications.dice.se Part designer, part producer, programmer and artist, what is it that makes a level designer effective? The short answer: knowing how to balance all of these roles to maximum effect! This session will examine situations from three AAA games, and the specific challenges they brought about and the solutions required to surmount them. Are level design approaches for radically different games inherently similar, or do accepted methods need to be drastically altered to fit the unique nature of the project? An examination of Alan Wake, Mirror's Edge, and Brink will help answer this question, and many others.
