The Pinside ranking is clearly manipulated, a place where most people basically pump the score of machines they own and lower what they do not own. Everybody do the same: differences among machines are negligible. Dont look at the POSITION in the ranking, but at the SCORE. N.1 is 8.9, n.100 is 7.7. Small difference. I believe that love for a certain theme influence at least for a 1/10. Hence, the top100 machines are very close.
Its rubbish.
