I think it's pretty cool, the game is based on norse mythology and the old guy was reading a passage from the old "Edda's", which are basically like the heathen bibles, and you should read them, some very good stories in there, although the rest of the video was about some kind of cyclical universe and a mechanical goblin or something, didn't find it very interesting.

Fun fact: the old man was speaking old norse, and modern Icelandic is basically just an evolved version of it, and being Icelandic, I could understand most of what he was saying :D but if a modern icelander could go back in time a 1000 years or so, he could probably understand most of what people then would say, but the people of that time probably wouldn't understand him :P end of lesson.... but i'm looking forward to this game!
