There's an interview with BioWare's Greg Zeschuk on Crispy Gamer talking with the BioWare co-founder about storytelling in games, touching on the interesting topic of story as a reward: "It's almost a sense of always providing the player a reward for their efforts. And a reward can be narrative. That's one of the exciting things that we've learned. It doesn't always have to be a big, shiny sword. It can also be an incremental change in your perspective of the world, or a little story bit that that really adds something. In Dragon Age: Origins there are these Codex Entries -- books that are all over the place. Lots and lots of them. You find them and you can go read them. They're interesting, well written and tell a detailed history of the world. And if you read them -- all of a sudden you're going to realize, when you go to certain places, that they're telling you something important about that place."
