That's indeed a nice feature, Skyrim is full of them actually. 40h within 10 days isn't so much, especially when considering that i didn't had anything else to do; i played both, Fallout and Oblivion much more than Skyrim. Not quite sure why, especially as i can only partially blame it on the UI and graphics, but it's a solid game for most parts. Well, i leave it for now, it will be there when i feel like it.

By the way: Skyrim got the same Metascore as Portal2. I know many agree, but i have mixed feeling towards this.
