In GDC 2011 session, Ubisoft Toronto's Patrick Redding explores game mechanics that help encourage cooperative play for the benefit of other game developers.
Redding makes a distinction between player cooperation as opposed to systemic cooperation before going on to discuss the lessons he learned during development for the co-op component of Splinter Cell: Conviction.
It was an insightful talk that's definitely still worth watching, so developers shouldn't miss the opportunity to do so now that it's freely available on the official GDC YouTube channel!
In addition to this presentation, the GDC Vault and its accompanying YouTube channel offers numerous other free videos, audio recordings, and slides from many of the recent Game Developers Conference events, and the service offers even more members-only content for GDC Vault subscribers.
