I also have a new and improved "CTB Wait Addon" for FF6, which makes the combat entirely turn-based, like FFX's "Conditional Turn-Based" battle system. For folks who don't like the time pressure of ATB

(I have already done the same for FF7 and FF9)

If you compare with vanilla FF6 ATB (below), you'll notice that the relative speed differences between characters are irrelevant, as the gauges fill up during animations and backlog the queue

The old "Classic ATB Enhanced" paradigm is still available as well

So I ultimately gave FF6 the same rule as my FF7 ATB hack: Time can flow during the current animation until any character is ready to act. This is "Modern ATB Enhanced" for FF6
