I can't wait until The Sanctum gets one and I play it. Only then will I comment on the gameplay, feel and overall mood it gives me.
As for Pinside ratings, they are horseshit and getting worse. It has turned into a pump and dump that I cannot imagine anyone would actually use them to buy or sell a game. New games are the worst since people would rate based on company. Games should not even be able to rate until 5 years out of production. Way too subjective and born from the culture of "what game should I buy" threads. Buy what you like!
As for the rating system I hope it is skewed so questions like "It is fun" is worth 50% and "cabinet art" or "repetitive sounds" are 5%.
I know there are players, collectors, restoration people, tournament players . . . but you can't satisfy everyone so if anything it should be tuned to people playing and having fun. Otherwise the granularity would be stupid. Imagine the system encompassing these type of people / questions like "Length of time until value increase", "Availability of parts and quality of reproduction parts" or "Does it have even scoring".
I'd rather judge a game based on questions that don't add to an overall rating but let you know about the game like this -
Is this game good for a small or larger collection?
Does this game have long or short ball times?
Is this game better as a home owned game for complexity and learning or a good one more game on route game?
