Its december and not a single word about the level editor :|
and it doesnt seen to be coming with the 12th update
I wouldn't count on it unless they throw it around the time the Ep Ardyn is released. I feel like the only reason why we are even getting the FFXIV Event was because it was already worked and a good chunk done based on the datamine. And for Ep Ardyn they are just reusing older assets; like I seriously doubt we'll see any new custom character models other than human Somnus or something that can quickly be made by their character editor. The pre-invaded Insomnia was technically already made they just needed it to be retextured from what the film used and optimize the poly count to something luminous engine could handle. They showed a game render of it in the Dossier when the Royal Edition came out so it seemed like it was already being worked on as well before the cancellation. I would be really surprised if we get any additional mechanics or assets whether in the Windows or console versions at this point unless they plan on doing something as a farewell or thank you when Ep. Ardyn comes out but even then it will be small or something they were close to finishing before SE decided to move on to other projects officially.
Edit: I realize I tend to naysayer all the time on the forum I don't mean to be. I rather just not give my hopes up. What happened to Windows Edition is kinda messed up and kinda blows that it was mismanaged too, like they spent way too much time trying to make it pretty rather than creating assets so it had longer playability. I feel like this game has been cursed from the beginning (It is technically the 13th installment if you don't count XI and XIV) and it's just been one disappointment after another starting from it's delay, to it's narrative changes to it's general release. Let's hope the FFVII (we'll find out in February) and FFXVI will be in a better state on release and better streamlined.
