I was working on my spreadsheet I posted here of the other games done by the Chrono Trigger developers along the way and I started analysing the real chance of the Chrono Trigger main developers coming together again to work on a new game.
A big factor we can't ignore is the estimate sales numbers of Chrono Trigger and Chrono Cross. I'm not sure of its accurary, but the info from VGHChartz.com tells us the Chrono series didn't came close to sell as much as the bigger Final Fantasy titles. So, as for the company executives, the series probably isn't on their minds.
Now let's go through each of the CT main devs.
<> Kazuhiko Aoki's (CT Producer) whereabouts is unsure. The last known project he worked on Square Enix was on 2008. He may be retired or in another company.
<> Akihiko Matsui's (CT Director, mostly for the battle system) whereabouts is also unsure. The last known project he worked on Square Enix was on 2002. is still working in the Final Fantasy series as Battle Designer (FF11&14).
<> Masati Kato (CT Story Co-Writer) is a freelancer right now, so he probably couldn't pitch the idea of a sequel to the company. The ideia would have to come from inside Square Enix.
<> Yuji Horii (CT Story Supervisor/Co-Writer) once said in an interview a few years ago he didn't have much interest in the series since all that he wanted to do he could do in the Dragon Quest series.
<> Hironobu Sakaguchi (CT System Supervisor) is in another company now, busy with their own games. Little chance he would leave Mistwalker for a while to work for Square Enix, except if the new Chrono game would be a joint venture, like the original was.
<> Takashi Tokita and Yoshinori Kitase (CT Directors) continue working on the Final Fantasy series. If they had a lot of interest in doing another Chrono game maybe they could make a good case to the Square Enix executives.
<> Yasuhiko Kamata (CT Graphic Director) left Square around 2001.
<> Masanori Hoshino (CT Graphic Director) has become a freelancer.
<> Tetsuya Takahachi (CT Graphic Director) is in Monolith Soft still working in the Xeno series.
As for the CT artists that could be invited...
<> Akira Toriyama (Character Designer) is busy with the Dragon Quest series and the Dragon Ball series. But, if invited, he could be in.
<> Yasunori Mitsuda (Music Composer) is also a freelancer now. Once a interview he showed interest in working on the series again, but said that for him is very important that Kato is involved.
So… basically… The main developers are totally scattered — a few through Square Enix different projects, some through different companies.
A new game with at least part of the original main staff involvement could only happen if there was a lot of interest from Horii and/or Tokita and/or Kitase part, and if they could convince the company executives to let them stop working on Final Fantasy and Dragon Quest for a couple of years and to let them maybe summon some of the other guys that are freelancer or in other companies now, and if the executives ignored the relatively low sales numbers of the series… Boy, that's a long shot.
Oh man... Are you hearing that sound? It's my heart breaking.
Let's look at it from another angle... Let's forget about the bigger-name guys and talk about the Chrono Cross team (although it was only compromised of around a fifth of the original Chrono Trigger team). Even most of them is not there. But, sure, they could easily employ Kato and give him a small budget and a new team made almost totally of new developers to try to create a hugely complex story to follow the overly convoluted and somewhat non-sensical story he ended up writing alone. But frankly would we care much for that?
As for me, what I'd like much better — and I think is way more possible and doable — is if they did a Chrono Cross remake. I don't think Chrono Trigger could get much better from a remake, but Cross could. I don't think Cross was a bad game relatively to the other titles in the era, but, unlike Trigger, I think it got several things that could be a lot better. The 3D graphics for one didn't age well (as most, if not all, of the PlayStation 1 titles). And I think the story had a lot of potential but is very apparent that it got rushed and messed up, and need a very large review, but they probably weren't given more time to do it or just didn't could do at the time. A lot of things in the story are not very well explained or are just very non-sensical (like Project Kid and the whole El Nido terra-forming/Dragon God thing). They could also cut a lot of hallow and uninteresting content, like focusing only on a few characters and developing them better (expanding Harle and etc.) and maybe even giving us better mid-game villains to fight than the Dragons. Also the balance of the game — from the very empty and slow middle part to the very rushed and frenetic latter part definitely could be distributed a lot better. They could also put in a better battle system, removing that multiple-choice melee attack system that was very annoying if you factor the amount of clicking you have to do versus the minor effect they have, and instead put something in that requires you to me more mindful. And that battle theme... oh god... that gets very annoying very quickly.
I hope the Final Fantasy 7 remake sells well and is well received. It couldn't hurt our chances of getting a Chrono Cross remake.
Anyway... If you have any information I don't have, or if any of this info is incorrect, please do share.
