Just the fact that they played some minimum amount should tell them the game contributed to the subscriber’s enjoyment of Game Pass. Otherwise if they are both selling a game and giving it to Game Pass subscribers for free I’m not sure what they are expecting. Can’t have your cake and eat it too, but I’m sure they would like that.
Maybe they are hoping that Game Pass is like extended demos and will lead to more game sales. But there are too many new games all the time for most to hold my interest.
