I'm sorry, my wording was bad. I essentially meant "unique users played the game", not monthly.MAU is a biased stat when you are comparing a multiplayer game against a single player one. Obviously a year down the line FH4 will have more MAU than Spider-Man.
Going by sales Spider-Man will obviously sell more than FH4 in the long run.
FH4 is essentially the first well-known and well-received IP directly launching on Game Pass. Will be interesting to see the numbers. I think some people will be surprised.
