Well I doubt the validity of this survey.
I can certainly agree that Playstation have been able to retain its customer base much better than the other 2. But brand loyalty itself Nintendo almost certainly win, just look at the longeivity of their IPs.
Isn’t there a difference between brand loyal to a company and one to a game? People will love Mario today when they played it as a child in the 80s. Or myself loving Halo but I don’t believe Xbox is lumped in with it. Like I could play it in PC if I wanted.
Imo Nintendo wins in terms of IP loyalty but Sony wins in company loyalty
