How does it simplify it?
Explain a 6.5 out of 10 rating for me.
7.0 generally represents an average game, below 7 is slightly below average, and above 7 is slightly above average...
8 and over generally are games that are worth looking at... that is how i personally perceive the ratings.

I can't buy this. Some won't even buy a game if it overall doesn't reach an 8.0 rating. So many people love Destiny, but can you imagine how much different the player base would be if people saw a like/dislike breakdown instead of this broken ass 1-10 scale?
