All I can say is this: I hope that the person who reviews BD tries to finish the entire game before writing his/her review. I don't care whether BD gets a higher or lower score, as long as both scores are fair and well deserved.
Not very fair for a reviewer, is it. Finishing a whole game -- especially games like BD or DD -- is quite time-consuming. Not to mention that games like, say, Sacred or Dungeon Siege hardly need finishing to be evaluated properly. You play it for an hour, you play it for a day, and the gameplay is still repetitive.
Besides which, 7.6 is being pretty damn generous. Bug-ridden and monotonous as Sacred is, I'm surprised it doesn't get a lower score.
