Don't understand your post, there is no "critic scores" on GoG. If you have the game you can post a review with a score, thats it, just player scores. The players that played Solasta liked it more than the ones that played BG3. I think this says something at least regarding gameplay.
I am not sure, do you not understand that having a higher review rating with 8 reviews (and not even that much higher of a rating), is not comparable to having a slightly less review rating with over 33k reviews? You cannot even remotely think that an accurate rating of approval shows it is a more popular game with a pool of 8 players opinions to 33k players opinions.
Don't know where those numbers are from but you are mistaking review for scores. On GoG you can post a review along with a score, but you can also rate the game without posting a review, therefore these numbers are not correct. The difference in scores has increased actually, Solasta is now at 4.6, this on a 10 scale system would be a 9.2/10, which would mean critical acclaim.
Don't know where those numbers are from? Directly from the store pages for Baldurs Gate 3 on both Steam and GOG. It isn't hidden. So I am guessing you have never taken a statistics course in college have you? having a 4.6 with like 8 or 10 reviews cannot compare to having a 3.7 with 33k reviews. The larger the sample, the more the review score varies. You are literally trying to judge a game to meet your own view of a game, buy saying "well game A has a 4.6 rating so it is better! But it only has 10 reviews so..." The score yeah of course the number on GOG could go up, a single poster from this forum could go post a 5 star review, and it would have a substantial effect on its overall rating.
