I'll bite. This has been discussed before, and I agree more ratings are needed. We call it the generic term 'rating', but that's what irks some. The 'ratings' as far as 1-10 or top 100 or whatever, are skewed mostly by the volume of games made/player access etc. But the real important part to me is the 'review' of the game. The reviews can give tons of info, whereas the actual listing in the 'Top 100' means little to nothing.
We need more reviews by folks who have had access to many machines, to compare and contrast etc. Some of those written by the pros here are great reads!
