The video might explain this for all I know (can't see it at the moment), but I really need to check what "turn based" means, because people call games like Final Fantasy VII and Final Fantasy VIII turn based, but I don't think they are.

Turn based would literally mean you take turns, but in ATB you can be attacked while selecting, so it's not really turn based. Or do they mean each of your characters take their turns? Either way, if I get my RPG done, I'm aiming for ATB, as it's part of the style/era I'm recapturing.
