I’m probably in the minority, but instead of a remake of any of the older games, I’d like them to just forge ahead with Final Fantasy XVI. I will admit that some of this just stems from me being tired of remakes in general. I know that franchise fatigue has been a thing in video games for decades, but it’s getting to the point where I actually long for the days of franchises getting a new installment every year or two instead of them releasing a roided out Greatest Hit.
I sort of agree, although I'm personally looking forward to the remake of Final Fantasy VII, I think any attempt to remake one of the other Final Fantasy games would be gratuitous and those efforts should best be used for Final Fantasy XVI instead.
Final Fantasy VII being remade gets a pass since it's pretty much the game that took Final Fantasy from a beloved cult classic series to a true household name and outright juggernaut of a franchise. The 2D games were successful in their own right, but VII is the one that the "normies" love the most. If you're going to remake one of the old Final Fantasy games, that's the one to do.
Personally, I think that the Final Fantasy VII remake is a case of Square killing two birds with one stone. They get to do the long-awaited remake of Final Fantasy VII that fans have been wanting since the PS3 was released and also get to use the remake of VII as a "test run" of sorts for Final Fantasy XVI.
Think of this remake as the "missing link" between Final Fantasy XV and XVI, it allows them to iron out the kinks of XV and possibly test new ideas for XVI. While I personally loved Final Fantasy XV, it did have a troubled production and the full version of the game will likely never be released since several of the the DLC's were cancelled by Square's higher-ups
I'm cautiously optimistic for the remake of VII, and while this is just the first part, I don't think it will be dragged out as much as everyone thinks it will be, especially after the issue XV had with the DLC's. I think the game will be a two-part or maybe three-part series at most, but I could be wrong.
