Just watched a gameplay demo for this game... and it looks really good, but it also got me thinking. What if this kind of gameplay carries over into other games? Well, if it does, I'll be very happy. This kind of exploration of the game world is something I love about the Elder Scrolls games, and it looks a though this game tries to go even more deeply into that stuff.
I really hope this does well and prompts other game developers to try and add something similar in their games, as I think more and more games would really benefit from this kind of thing.
