I am pretty new to BGA, so forgive me if this is already explained somewhere that I have missed:
I was wondering if the rating system for games on BGA is just a straight mean of all the scores (although it translates star rating 1-5 into a 1-100 score seemingly?) a games is given or if there is a more complicated system at play (not that complicated would necessarily mean better)?
Similarly how do 'rating' and 'popularity' differ on BGA
I was looking at the highest rates games and a good majority were expansions. I was wondering about the inevitable bias these will receive: if someone likes the game enough to buy an expansion they are likely to also enjoy the expansion (obviously not always but an expansion will be naturally filtering in a way that a base game is less likely to) and if anyone had thoughts on if/how to accommodate this in the rating system?
