Dark Messiah is an awesum game!
Graphics wise... I would say is incredibley good it's very close to "Elder Scrolls: Oblivion" just a bit lower if you take a closer look at the game!
The story for me is better than Oblivion's I'm serious! In Oblivion you write the story... In Dark Messiah it has already been written.
The gameplay is very much like Oblivion just alot less choices to make... Well because you already have a main goal I don't think alot of choices were ment to be made!
Overall I would say this is a great game... One ment to be played for those who're into adventure games!
