Right now, the biggest range between two reviews is 2 points. So if the first review is an “8” you know the second will be anywhere between 6-10. I think there should be a greater potential range between review sources… One could give a 5 or a 6 and the other a 9 or 10.
Also add some more review sources with preferences and biases… some review sources would prefer certain types of games and the scores would reflect that somewhat.
