Damn you Nat!!!
Good stuff, huh? That video is courtesy of our own Black Tiger. Did you watch the entire thing? It's quite long. I only watched a couple minutes cuz I'm at work and actually have stuff to do, but it shows the game being played as a character I've never played before.
One of the big draws of this game, something that really ups the replay value, is that your actions during the first 30 seconds of the game determine who you will be for the rest of the adventure (your "class" essentially), and the story varies depending on this-- affecting the way the game plays out.
