ArenaNet's Cameron Dunn discusses technical challenges in creating Tyria

If you can't get enough Guild Wars 2 and like taking a peek behind the curtain to see how your favorite game is made, this one's for you.

GDC Vault is a treasure trove of information, collected over years of presentations from Game Developer's Conferences held around the world. While most content is available only to past GDC attendees, they also release a smattering of great stuff for free.

The latest entry in the free column is a talk by ArenaNet programmer Cameron Dunn entitled "Guild Wars 2: Programming the Next Generation Online World." He gave his talk last month at GDC Online in Austin, and it's a real treat to watch.
