It's interesting that not a single review has been scored below 80 so far... I wonder if there are some reviewer (maybe a smaller market/niche) that hates the game? It's an oddity to not see a single outlier in the review data set.
Granted it could just be that everyone loves the game, but I would think there would be at least one curmudgeon (nothing is ever going to be as good as Quake/CS/Goldeneye) in the media pool.

Although other AAA games don't seem to have any low scores either. Mass Effect 3 hits 75 for the low point. Same with Borderlands 2. Fifa 13 doesn't dip below 80.
