So what might the innovators at Square Enix come up with, when programming the new battle system for Final Fantasy XVI?
Well, we know it’ll be an action JRPG. Well, we don’t know that for sure. But, it’s likely, given Square Enix wants to compete with the video game market. But keep in mind, they want to crush the competition.
May I make a suggestion? Rhythm-based gaming. How would this work? Let me explain.
You see, rhythm games are a subset of the action genre which challenges a player’s sense of rhythm. Of course, these games:
Games in the genre typically focus on dance or the simulated performance of musical instruments and require players to press buttons in a sequence dictated on the screen. Doing so causes the game’s protagonist or avatar to dance or to play their instrument correctly, which increases the player’s score.
So will all battles keep rhythm? No, not necessarily. They could, and maybe staying on the beat could give you extra power. Certain areas light upon the enemy, with certain body parts, to hit corresponding to certain buttons. Maybe this might cause the enemy to stagger, like in Final Fantasy XIII and XV.

Simply attack the enemy with magic or a physical attack, and buttons will pop up in a sequence. Think about this: it would be a new style of “turn-based”. It’ll give you time to input commands. A mixture of the new and the old to satisfy the old and new players.
