Quoted from CaptainNeo:

it never was number 1. The ratings are flawed. People don't give legit reviews. They rate and buy games based upon what people think are popular. Not based upon actual play value. Sure MM has a great toy, but the layout is lackluster and the rules are meh. Plus you have 5 other games with the exact same layout and rules. Should not be ranked as high as it is. MM lasted 3 months in my collection. Was not worth keeping.

Quoted from koji:

Yeah, I definitely would not group the games.. particularly for Sterns, it seems like there are potentially major art, playfield and rule differences, to the extent, that I might rank one version particularly higher than another.. sometimes the pro, sometimes the premium.. but they can play with enough differences that it would definitelty affect how I would recommend them, if say, only one of those variants were released or available.
I was not trying to specifically remove or add any title to the list. I actually like JP... if someone offered me a choice to gift me one of the two machines, I'd need to give it some serious thought.. but these ratings are not the single overall impression of the game, they are rather a combination of Art, Sound, Toys, Gameplay etc. so although something like MM might begin to fade so far as our modern level of more complex and deep rules and shots, that is just a single facet of the ranking, (unless I am arbitrarily increasing another attribute, because I want my overall to be increased (which I think many people likely do...)).

Quoted from underlord:

I played MM on location in the 90’s . . . Just a very balanced game.

Quoted from Flynnyfalcon:

My biggest issue is once a new pin makes it into the top 10, usually pumped up by excited owners, the MM, AFM and MB fanboi’s come in to hate on it. Like absolute clockwork, bringing their pride and joy back up the top.
Do they not realise how the algorithms work? Once enough people have played the new game, and voted truthfully, it’s place will correctly settle. Heist is maybe the exception, as majority of voters will be owners given the lack of Multimorphic out in the wild.
The fools who vote 0’s and 1’s for these amazing new pins should be called out for their part in ruining the Top 100.
Maybe a Wall of Shame for most 0 votes etc would entice some users into actually using their brain. Adding an avatar or icon to show this in their profile etc.
Pinball is subjective, but objectively, no pinball machine made in the last 20-30 years is worthy of anywhere near a 0, in any area. Not even Thunderbirds.
AFM, MM, and MB are great pins in their own right, I’ve owned two of them, but they didn’t last long. I rate them highly, but in a home environment, they got stale pretty quickly.

Quoted from palmab03:

There's zero reason to rate each version of one game individually. Drives me nuts.
