Now obviously, this is NOT confirmation of anything, but someone on Discord brought up an interesting observation...
...in that this game
might be developed by NDcube. The cited reason is the general UI for their games, and perhaps the graphical style.
I am not sure a comparison might help in elucidating how I feel about it, but here they are:
If NDcube really did this, I think it's great for them! It's nice for developers to break their mould, like how Mario Kart developers did a fighting game (ARMS) or the Animal Crossing developers did a shooting game (Splatoon). Certainly it's a remake, but what if (what if) NDcube might step up as another Mario RPG developer?
NDcube is one of the most underestimated developers, especially among the hardcore crowd because they develop casual-focused party games, so like despite Mario Party being a heavy-hitter in terms of selling a lot, they tend to be dismissed as an essential member of Nintendo's team. Not that I think of it, because I believe that NDcube provided a crucial diversity within Nintendo's offerings and they are a positive contributor to the team.
Thank you for reading.
