I understand that Ys III as a whole is extremely different to that of Oath in Felghana, but the point is, they are both still action-based. Things happen in real time, enemies and Adol move around the field actively, and pressing the attack button equals to an attack in real time.
FFVII was turn-based/command-based/menu-based. Enemies don't move around, things do NOT happen in real time for Cloud and party unless a command is selected from a menu. It did have some "real time" element because enemy can attack at any time, but you cannot physically move around from the attack because your characters are fixed in a turn-based fashion, you perform action strictly by selecting commands. In FFXV, everything happens in real time. There is no command to select, there is no menu, enemies and Noctis and AI partners can move around at all time, actions are happening in real time. FFXV is an action RPG.
