For me, this game became a paradox, because I still didn't understand what they wanted to do with this game.
As a FF, this is a very bad and weak game, since the depth was sacrificed, a straight-up liniar game without any RPG elements, where practically everything from equipment to stats has no meaning. A completely dead and useless world, in which there is no point in running, since the reward for this is 0. Plus a relatively weak and uninteresting plot.
At the same time, the game tries to be in Devil May Cry, but this is an extremely meager and weak attemp. As was correctly noted, the difficulty of the game is absolutely zero. And please fire the person who came up with the idea that you can complete the game by wearing 3 rings and pressing one button...
You either make FF, or if you really wanted to make a DMС clone, make DMС to the end. In the end, you got a game in which part of FF is Bad and part of DMС is extremely mediocre.
But the main mistake in my opinion is that this is a numbered part of FF, if it were some kind of spinoff like Dirge of Cerberus, there would be much fewer questions. But as a numbered part of FF it is incredibly weak.
