Don't know about others, but I don't look at ratings to decide which game *I* like or want. I watch a video, load it on VPin, play it the real thing in person if possible. It's not like Yelp where you can make informed decisions about quality/service when you want to eat out for a one time event. It's personal. There are games I have loved others hate, and definitely vise-versa.
Ratings are interesting but not useful -- i.e. trying to compare Elvis, Led Zepplin, Duran Duran, Spice Girls, and Snoop dog just because all of them were ranked #1 at one time for their era; when I only have interest in a couple of them myself and the others could be ranked at #100 for all I care.
Rankings only lead to pInflation and unrealistic expectations (on both sides). Trying to split it out is a waste of someone's time which could be better spent playing or fixing
