I've been quietly following the video game scores dispute saga for the last few years and I find it amazing that things have escalated to the point of actual lawsuits over the validity of old video game scores. Frankly, video games are supposed to be fun, and most points of contention could have been easily avoided if people had simply given it a modicum of thought.
In my opinion, the entire concept of keeping track of who's the "best" at playing any particular video game has been flawed from the very beginning, especially when using a simple score as the sole means of ranking a performance as compared to others from the beginning of time. Factor in the baggage associated with old scores, and you ultimately end up with a bunch of cranky middle-aged men arguing over decades-old video game scores. Sound familiar?
Accuracy aside, when you say someone is the "best of all time" at playing any particular video game, there inevitably comes a point when scores get so high that they're completely out of reach for anyone but those who are compulsively obsessed with being the best of the best, where you eventually end up with a list of "top" players with the same high score. Obviously, someone will have done it "first", but does it really matter? It's a freaking video game, not the first man on the moon.
That being said, I believe there's a better way that's far less contentious and much more inclusive of casual and/or first-time gamers, without all the baggage associated with crusty old video gamers and their scores, often with questionable origins. Think of it as a rotating list of "champions", but only for a limited period of time.
Simply have two types of published scores, verified and unverified, with a given set of rules established to qualify a score as being verified. And don't bother with selected lists of video games, as getting it right would be akin to herding cats. Let people post scores for any video game they want, categorizing them accordingly, but to be "verified" it must follow the rules.
Last but not least, the time period should be limited to one year, as opposed to forever. Think 2021 video game scores, 2022 video game scores, etc. Forget about "video game player of the century" and focus on "video game player of the year" for any given video game title. After a year has passed, the previous years scores should be archived and the slate wiped clean for the coming year. By the way, time limits have the added benefit of allowing rule changes to be incorporated for a new year, without affecting any previous years scores.
As for the existing database, which can never be fully authenticated due to it's questionable origins, I would simply archive it for posterity and look to the future. Lose the baggage of the past and focus on having some fun for a change. On the other hand, if herding cats is your thing, good luck with that.
