I think given Disney and SE will want KH4 to be a huge success for them, they have and likely will invest in a lot of cross promotional content. Fortnite makes a ton of sense, and I wouldn’t be surprised about active Disney games like Dreamlight Valley, Twisted Wonderland, and Lorcana (lord people don’t do this to us bc I don’t have it in me to not buy these decks and cards in the service of KH) featuring KH. And of course non-Disney stuff beyond Fortnite (don’t ask me what because I don’t play mobile games).
But obviously I think all of this will be in service of being promotion for KH4, positioning it as a key franchise for both companies, which requires maximum Sora-synergy everywhere feasible. This isn’t some unique thought, either. This is just clear, obvious marketing potential after the fervor that was apparent from Smash. And I’m sure plenty of these collabs have been multiple years in the making.
So yeah. Idk why I felt compelled to say any of that. I guess waiting for my doctor’s appointment made me a bit rant-y.
