People are going crazy for KH3 right now, Disney is pretty much a timeless thing that spans generations of fans.

Square have also played it smart by releasing the digital All-In-One collection which I wouldn't be surprised if a lot of first-timers have picked up to get ready for the main release. They're making sure that KH3 is everywhere, even at things like D23.

Also, Union Cross seems to have been a hugely successful mobile game for SE, that has a very young following.
