I think you guys are missing something here.
Ratings need to be updated as time passes.
MM might have been a "Perfect 10" the day it was released. Maybe it still is but games will (or should) diminish in ratings as other newer games are released.
As per some of my other posts, if you had put an AC/DC or Tron beside an MM way back when, I think it would have blown MM away with the LEDs, sounds, etc. Nothing against MM, but generally speaking, the older pins don't hold up to the newer ones in reality, yet they are still in the top spots on the charts.
The exception to this of course, is fun factor. Maybe MM IS the most fun game out there. If it is, that's a great reason for it to maintain the top spot.
The only way I see these ratings being more accurate is a combination of current value (average of recent sales -good luck inputting all the data) and if everyone were to update their reviews/ratings on an annual basis.
Of course, with more TAF owners out there than anything else, TAF might be swayed a little but then again, you're never going to get it perfect.

That's a very valid point (that no matter what, people's opinions will vary) and it reminds me of something a friend said recently that I agree with wholeheartedly as well:
Pinball technology hasn't changed much recently so the games that were fun initially, are still fun. Sure, AC/DC has a cannon, but MM has a castle... TOTAN has a Genie... TOM has a trunk...
I suppose when you take the older looking games and add LEDs and mods, it really does put them on a level playing field (or very close to it) to compete with most of today's new releases.
If that is accurate, then the ratings really ought to be all about the fun factor.

I didn't say it was a fact. It's my opinion. Most comments on here are, no?

And I'd be open to hearing anyone explain how Indiana Jones is rated higher than Tron and AC/DC.
Especially if you can also explain why IJ isn't worth as much.

Here's a question: with a few exceptions (like BBB, for example), should average selling price replace the overall rating? People are voting with their dollars, no?

Disagree completely. We aren't trying to determine the best bang for your buck/dollar value, we're simply rating them to see which game is best.
Price should be ignored completely.
