It's a remake that came out recently, so it's understandable that most people who played it are already Type-Moon fans. I'd say, the rating is likely to fall in a few years.
And, honestly, Fate is classic, but it has quite a few flaws, and the translation is terrible.
I agree, but it makes it easier to find these niches. I guess, when I just started reading VNs, I mostly played either highly rated VNs, or the ones that had interesting reviews. I guess, this change would make my experience back then quite different.
