Maybe I was different from the modern day teenage Fortnite crowd but at that age I was deep into story based games that were able to keep my interest and get their point across without the kind of preaching both XIV and XVI engage in and most if not all were entirely void of the goofy elements allegedly supposed to appeal to those sort of gamers.
For all the attempts to appeal to fans of the FF series you would never have gotten me as a hardcore FF fan to play this game with stuff like the Fall Guys collab front and center, it is an active turn off when my interests have consistently been aligned with an entirely different tone and setting.
The people into that other stuff aren't likely to start playing FF because of these collabs. They are, as I was, largely content to remain within the spaces dedicated to the source material.
