I know I’m late to the party but I just found out and didn’t find a post regarding this
TL;DR: Steam now calculates review scores based on reviews made on your languages only (if enough). This is on by default, but can be reverted to go back to review scores based on all reviews (from people that purchased the game directly on Steam only)
fair enough, youtube probably wasn’t a good comparison, but GOG should be. They have written text alongside the 1-5 star review. Now, there are grades 2-4, but in general 1 and 5 seem to be the most used ones.
I would argue against this. I have seen more diverse rating, but 1 to 5 still isn’t really accurate
GOG also has a massive problem: you can’t edit your review once you published it
