Final Fantasy 7 Remake has a “classic mode” that makes the combat play like that of the original game.
As revealed on-stage at the Tokyo Game Show, Final Fantasy 7 Remake’s classic mode recreates the combat mechanic of the original Final Fantasy 7, in which you’d wait until the ATB Gauge filled up then selected a move to initiate an attack.
As a reminder, here’s a clip of Final Fantasy 7’s combat:

In the standard modes of Final Fantasy 7 Remake, the ATB Gauge fills up by repeatedly attacking your enemy. In classic mode, this part is handled automatically. So, you don’t have to do anything and your character fights automatically, charging up their ATB Gauge.
