Don’t get hung up on ratings - they mean very little. Play and purchase what you like.
There are multiple angles at ratings and many “reasons “ why they rate.
Think about Monster Bash ratings given 10 years ago on Pinside. The rating system has changed over the years - how did Pinside “normalize this?” You would have to clear all ratings and start over.
This is 1 of many reasons I don’t pay attention to ratings.
