Feragoh, I agree. The whole Christian rating can be a somewhat confusing area. Keep in mind, first and foremost, the Christian Perspective section is there to simply give an account of what may be offensive to people. Some people may not be offended by the blood, but others will. We need to relay information in the review so people have a full understanding of the game's content without any surprises.
And although the Christian aspect may skew the result, the reviewer also has a little discretion as well to edge it up the other way a wee bit.
But overall, the reader should read the review to find out the ins and outs of the game. If a game got great gameplay, sound, and graphics, but the Christian Perspective brought it down several percentage points, the reader can look over the possible offensive content to see whether or not they will play the game.
