Back in November, Josh Sawyer gave a presentation about Pillars of Eternity (still known as Project Eternity back then) at the GDC Next conference. The presentation slides were released soon after that, but the video of the presentation remained locked behind a paywall at the GDC Vault website...until today, that is, when they released it for free. Yay!

The presentation is half an hour long and covers a variety of aspects of Eternity's design, such as difficulty modes, graphical style and user interface, and the game's textual nature. There is also a large emphasis on the technical challenges of rendering the game's large prerendered levels and combining 3D characters with 2D environments. I think I can also claim some responsibility for Josh's answer to the question he gets asked at the end.
