I couldn't agree more that the ratings need to be consolidated. Sure, there are some feature differences, but the overwhelming majority of the game is the same. Although I don't think ratings are everything (after all, I do have a Popeye in my collection), I enjoy sometimes browsing the Top 100 List and I would welcome seeing more variety in it.

I also think there should be a way to list how many games you've played on a particular machine when you rate it. There could be some behind the scenes formula that gives weight to your rating based on the number of games you've played. For example, a rating from someone who has played 25 games on a machine would be weighted slightly more in the game's total ranking than a rating from someone who has played 3 games. I hate reading ratings that say "I walked away after my second ball" and then that person posts a review bashing the game. I know how subjective reviews and rankings are, but I don't know of any pinball machine that could be fairly rated after playing less than a handful of games.
