I've been watching some Skyrim Behind the Scenes on Youtube. I'm always pretty fascinated by watching masters talk about and show their work. For me, it ads to the experience in a fun way rather than deconstructs the game. But, sadly, too many times they're just shallow promo videos that barely say anything worthwhile.
I don't really know how to seek out Behind the Scenes of games, often it's exclusive to the collector's editions. But if you're just as fond of this stuff as me, I'll gladly take some tips. The meatier the better, production quality isn't that important.
