Yup, there's not a lot of people that finishes any given game.This is incredibly disingenuous. You know what that number is for Red Dead Redemption 2? 23% Control is at 28%. Doom 2016 is at 17%. Are those bad game's? Also, any title that's on GamePass is going to skew lower, due to the fact that people might be trying the game even if they're not interested in it. You used to have to make an upfront commitment (increasing your personal investment in completing the game) for games, but that's not the case anymore.
On the bright side I noticed though that it means that when playing a game on Game Pass, if you like it and stick with it, the second half (or more) is rare achievements galore hahaha
