No, you've skipped a step. We're treating Metacritic as an accurate metric of how good a game is.
No; you are using loaded terminology which is why I questioned your methodology and your conclusion.
To remind you:
it's getting great games at a faster rate than any previous platform.
Metacritic is
not a metric of how 'good' a game is, let alone an
accurate one.
Metacritic is an aggregate of
critical consensus.
In fact, it is not even an
aggregate of critical consensus, because it does not use a system such as RottenTomatos does to determine a percentage of critical consensus, it uses a mean average of critical scoring.
And in fact it is not even a
mean average of critical scoring, because it standardises disparate review scales into a percentage.
And in fact it is not even a
standardised mean average, because it uses a non-public weighting system to lend more credence to some publications over others.
And in fact "good" doesn't even come into it because "good" is a subjective quality - there is no 'gold standard' of 'good videogame' against which all other products are tested; if anything what a metacritic score tells you is how closely a product aligns to metacritic.
So what a metacritic score is actually used for - explicitly in the way its data was framed in this conversation - is as a barometer of likely demand. Publishers do not pay metacritic bonuses because they find critical acclaim inherently worthwhile - they pay them because there is a high correlation between critical acclaim and sales. A game being "good" is not part of that equation.
As to your "time" emphasis, I would question the methodology and conclusion of someone making the claim "The Xbox One is the console with the highest number of 85+ metacritic titles in the fastest time period ever" the day after backwards compatibility was added
for the exact same reasons as I am questioning your framing of the data.
Metacritics methodology might say that a virtual console release on a nintendo console, a title being added to a backwards compatible emulator whitelist on an xbox console, and a PS3 title being recompiled for PS4 are all
completely different things where only one will get a new entry as a new title, but customers will not and do not see that distinction.
e:
TL;DR
"At this point in its lifespan the PS4 has more 85+ metacritic titles playable than other platforms have had" - thats fine (if true, I don't care enough to check, I suspect it to not be true though).
"The PS4 is getting great games faster than any other platform has ever had" - no, that is reframing data
