With a few changes to the button layout, the game could be fully functional with a Dualshock 4. With the touchpad, all the reality shifts become a simple swipe with the thumb. And trust me, it comes naturally. I played Tomb Raider on the PS4 which utilised a thumb swipe to light the torch and that became second nature when it was time.I may sound like a total cynic, but I just don't think that KH 3D HD makes a whole ton of sense right now, for three reasons:
1. The game is designed for the 3DS.
Dream Drop Distance, unlike Birth By Sleep or other titles was made for a current gen system, moreover it was designed specifically for the 3DS. I think that due to this, they couldn't port it to a formal platform unless they ported it over to the Wii U, which to me is the only system that could support dual screen platform play. This was the case with both of the other DS titles, which were passed over due to the fact that they would be very difficult to port to a non dual screen system. If they did this however, it would kind of subvert their plans to have all the games on one system, and would kind of defeat the point of it being remade in the first place, and boil it down to merely a graphical and hardware update.
Also using the touchpad as a button would allow people to bring up the detailed maps. That way, all that work and detail isn't squandered and it's kept in tact.
It may not have the most worlds in it, but that doesn't mean it's the shortest. Dream Drop Distance surprised me by how long the game actually is. I was not expecting a 35-40 hour game.2. Kingdom Hearts 3D is the shortest game in the series.
Yes, I said it, KH3D was just a short game. Almost every other Kingdom Hearts game features at least 13 unique worlds, whereas DDD only had 7 worlds. If you count the worlds twice because of the dual story lines, I suppose you'd end up with 14 worlds, but there were really only 7 -Levels- per se. Besides, judging by that rule, Birth By Sleep would have 36 levels, since each character featured a total of 12 playable levels. Due to this, I don't think they'd be able to realistically push their efforts from Kingdom Hearts 3 just to churn out another remaster, especially since it'd be stand alone. There are no other games left to package it with, so it'd be kind of underwhelming.
They wouldn't be "pushing their efforts from Kingdom Hearts 3" to make this. There's already a team who made 1.5 and 2.5, right. That team remastered 2 games and made 3 hour cutscenes for another. Take a handful of those people and you have a team who can remaster only one game. The rest can be absorbed into the Kingdom Hearts 3 team.
The game features somewhere between 6-7 hours of cutscenes I think. I do not want to have to watch 6-7 hours just to get a story. I'd rather play it and enjoy it. Especially since flowmotion is a fantastic feature that people should probably get use to before they play Kingdom Hearts 3.3. They could just cover it in cutscenes in KH3.
In the previous Kingdom Hearts titles like 3D, for those who had not played preceding games they featured articles, or in 3D's case the chronicles sections. Also there were optional cutscenes which explained the storyline of the game, as well as the backstory of others. Several people theorize that just because it was featured in the credits of 2.5 it must be its own standalone game. I think it more likely that since it was included next to footage of 3, it'll most likely be included in 3 as either a way to catch people up via cutscenes, or chronicles. After all, the game was just a big filler until the end anyway, as basically nothing of substance was revealed until the game's climax, other than perhaps the Nobody's return.
