"It’s been 11 years since the original game was out and now we’ll have Kingdom Hearts III at some stage in the future," he said. "The people who played the original game, at the time they were probably around 12 or 13…but now they’re in their twenties.
"While fans of Disney are usually quite young and Final Fantasy players are much older, they come together to create a Kingdom Hearts audience that’s very unique. The feelings people have towards the series are so deep these days because they spent many of their teenage years, which is a very sensitive period of your personal life, with Kingdom Hearts."
But what of the future of the series? By its very existence, HD 1.5 ReMix creates an expectation that the second cycle of Kingdom Hearts games will be getting the HD treatment. The fact that a series of high-definition clips from Kingdom Hearts II, Birth by Sleep, and Re:coded make an appearance in the closing credits of HD 1.5 ReMix seems to all but confirm Kingdom Hearts HD 2.5 ReMix is on the way, but Hashimoto isn’t prepared to make it official just yet. "If everyone plays 1.5 HD ReMix, if everyone likes it and everyone supports us, then 2.5 HD ReMix could happen," he says. "So at this stage, we just have to encourage people to play 1.5 HD ReMix!"
"The fact is that the main focus of the series is Sora and Riku; how their friendship develops, but also how they grow up," he says. "After so many years, the players’ personal growth is closely tied to the game’s story at this point, so that’s the most important thing about the series and what we want to put into the game. For Kingdom Hearts III, players will be able to resurrect the happy memories they have from being teenagers when playing Kingdom Hearts III. So it’s very contemplative, and will match the personal experiences of much of the audience very closely."
