“What’s important to us is putting the games out that we want to put out”…
I've actually been surprised but how many gems I've found in games with a 70% rating or a 82% rating. Sometimes ratings can be impacted by feelings about a company or a media incident when the actual game is rock solid.
I wouldn't say those numbers are for games that suck, anyway. That's a decent, just not mind-blowing game. Anything that's 40% or lower is what I would say almost universally sucks. But I would also take into account review bombing for things beyond the scope of the game itself, as it is very often reported on when it happens.
Open critic has a handy chart available for scored titles that compares it with the rest of their database. This offers some insight into the score distribution:
So a score of 70 is already pretty mid, and 60 or lower is going to be dire.
