Which did you enjoy the most. For me it was definitely the "Technology Behind Skyrim" one. It was the only one that actually INTENDED to reveal significant info about the game (well the Lore one sorta did, but that was almost completely a recap) and it gave us a glorious (and accurately shadowed >_>) screenshot.

The upcoming Combat update... naw but Sounds of Skyrim for me followed by Technology behind Skyrim and Todd Howard Interview(s), video 2 to be exact.

All had their charm - it's what I would commend GI on most, they have varied the medium and content greatly.

Sounds of Skyrim for me. Tons of interesting info and trivia on an aspect of making the game. Plus awesome snippet of the OST !

Sounds of Skyrim was pretty neat

Behind the scenes, all that concept art. If Bethesda released a book with all those lovely drawings in, my coffee table would be even more cluttered, and my wallet even lighter, both of which would violate the laws of physics.
