Again, what you love in a story may be something that I find make me snap the disc in two.

Thinking about it, the best way to 'grade' games may be for every user who reviews the games to have a favourites line onto which they place the games they review in order from most hated to Holy Grail (I'll make a mock up of one when I've got the time). That way, the game is still rated, but as a comparison with other games, rather than a simple number - any ratings are thus made more meaningful.
