Been playing two hours of Darksiders on my PC, after getting it during the sale. It is awesome, but that is not why I am typing this. The reason is this: every time I blow the horn "Earthcaller" I get the feeling War is only dreaming... 
At the 7 minute mark here you can hear the Earthcaller. 
While you can hear the sound I am thinking of here. 
 
This makes the game a lot deeper, and more meaningful. GOTY 2010.

cool

Someone needs to mod it to sound like a vuvuzela

Man I should really play that game again.
So good.

Playing the game right now, got it on Steam cheap, it's better then I thought it would be
 
The game is pretty dark
