Add in some 4th wall breaks and we got ourselves Deltarune
Interesting. I suppose the idea of parallel realities is similar. KH has regularly explored digital worlds, too--Roxas' parallel Twilight Town, the inside of the journal in Coded, Ansem's computer (Space Paranoids).
Forgive me if this might be a touch off-topic, but I couldn't help being struck to see a topic with this title appear right now. Just a few days ago, in the Keyblade thread, I had been thinking of how KH2's dilution of the Keyblade as a Chosen One exclusive weapon to everyone having one reminded me of the way Adventure 02 obliterated the rules of Adventure by giving everyone and their grandmother a Digimon.
And while already on the subject of Digimon parallels, as a child, Sora and Kairi always reminded me of Tai and Kari in Digimon Adventure both because of their designs (Sora's gloves and hair, a great deal of Kairi being like Kari) and Kairi's name being similar to Kari's on top of it. Sora's personality is entirely different though, less jerk than Taichi, but Kairi being a critical figure of light is very much in line with Kari (Kairi's Dream Eater even ends up being a cat, like Gatomon, lol). That may be part of the reason it's hard for me to see the two as love interests, since Kari was Tai's sister. Come to think of it, the adversarial relationship between Taichi and Yamato is similar to Sora and Riku in the first game as well, even though Riku looks little like Yamato.
Admittedly, I think these were / are things common to a lot of anime and anime-esque video games like Final Fantasy, but I couldn't help relating KH and Digimon to each other back then considering they were out around the same time as one another.
