If 7 is mediocre games than whole scale is 3-10, slightly shifted up but not much. Mediocre means that they are in the middle of scale.
well that is how fucked the scale is. a 7/10 is a game people wouldn't instantly dismiss, but a 6/10 is.
it's not following any logic at all, so you can't apply logic to it by trying to reason which would be the middle of the scale.
the reality is a 7 is mediocre, a 6 is basically an "avoid", and an 8 to 10 is just good, good+ and good++
anything below a 6 is only really used for actually broken nearly unplayable games so it's not even really part of the scale, as it's just a 6 but also broken... and with 6 already being an avoid, avoid because broken doesn't change much lol
Players here has the blame too - they put expectations way too high so they think that 6-7 games is already a "bad" games while they just mediocre and unimpressive. Some of these mediocre games actually go well in niche, they just can't appeal for many. And there are tons of really trashy games which deserve 3-4-5 score, but they just ignored.
yeah, this is one of the reasons I cringe every time when I see these review threads of new releases on here, which mostly revolve around people predicting reciew scores and/or discussing the aggregate scores.
Eurogamer did it right when they removed scores and just had 3 labels and non-labeled ones. but that stuff doesn't work well in online discourse and aggregate sites, which are essential ways to get people to click on your review, so they chickened out and went back to a more traditional scoring system
