At a GDC press conference, Insomniac Games (responsible for Ratchet & Clank and Resistance: Fall of Man on PS3) has announced a ground breaking initiative to open up their technologies for the development community at large. Through the "Nocturnal Initiative," Insomniac Games is attempting to break the common development practice of keeping technological advances a close-guarded secret. As they noted, "developers spend resources solving problems that have already been solved."
A public site (noctural.insomniacgames.com) will give developers access to various parts of Insomniac source code. Libraries have already been made available, with more on the way. Through a Wiki-style interface, Insomniac hopes that they will allow everyone to "make better games."
