I admit that I have raised ratings on levels, but only a few times. I've actually done more than that, I've even rated levels just to raise the overall ratings. I am more concerned with the overall rating, and getting the level spotlight, so that it'll be noticed and possibly even played. I believe had it not been for me, levels like atom heart would not have been played as often. You see, if people want me to rate absoloutely stricly, then I will by all means be 100% consistent with all my reviews. However, I am concerned with playability and popularity of levels.
