Yahtzee brought up a bunch of points which were valid, but the point is that it was intended to be kind of a rip off of Legend of Zelda...Joe Madureira (sp?) even said as much. I enjoyed the game a ton, as I kept picturing it as LoZ, but with a really badass viking / hell's angel as Link. Sure, it's derivative (really, really derivative) but it does so many things right. I personally really like the stylized, kind of cartoony art, and it was also great to see an apocalyptic game which doesn't follow the brown - on - grey color palate (Darksiders is pretty colorful. The voice acting (with the possible exception of War) is pretty great...Mark Hamill makes a great villain. And I swear Samael was played by Killface. It's definitely worth your time to play it. You may not get 60 dollars of enjoyment out of it, but I sure had fun.
And yes, I do like Warhammer.
