Even when I play a game like Assassin's Creed , I will sometimes just sit at a bench and just watch. Because I want a break. How much detail have you put into plants and animals, lakes and mountains--the natural side of things? A lot. Coming off of Fallout 3 which had very little of that, the world was destroyed. We came into this with more joy to create trees, and plants, and flowers, and waterfalls, things that are more beautiful to everybody. And now when you pick the plants you see them being removed. This game has herbalism in spades. And then you feel guilty if you walk by a plant you could've picked. You are like, "I guess I will turn around and pick that." We have a working ecology: foxes that run around, that get hunted by wolves, that get attacked by mammoths. And they all have different kinds of meat you can get out of them, and then cook those meats. So the game works on two levels: you have the minutiae that I just talked about, but then you have these big battles with dragons. You have that, and everything in between. Speaking of dragons, there is a dragon language. How was that created? We knew we were going to do the dragon language, and it was going to be a gameplay device with these "shouts." I don't know if you have heard the music for Skyrim , where you have this barbarian choir singing.
