Yes, I did finish the game and I loved it. I do understand where you are coming from, was just having a laugh with the "I want more of the same, but different!" statement
The missions did get a bit repetitive, I agree. You didn't HAVE to get all the clues to get the kill though, has to be said. I personally found the traveling between the cities (before you could port there) to be more of a chore. I enjoyed the game play, the combat was fun, the mysterious storyline and the spiritual undertones.
And I did collect all the clues in every city before every kill. And I really didn't mind the repetitiveness of it at all.
