From I see looking at the top 100 is not too much change over that last few years I've been looking. Yes, some newer games have moved up, but I agree because I tend to like the newer games. The biggest change is Cactus Canyon moving down significantly. I had a chance to play that pin one night and spent a good amount of time on it, and it is probably one of my best rated games. Adams family has moved down; big deal. The newer pins that have moved up I believe deserve it.
The only weird one I see is Dialed In at 6. I've never played it, but maybe it's that good.
I roll my eyes at those that rate something 10 out of 10 though.
