I've heard it's possible to kill the machine that chases you out of Dollet, but I've never done it myself. I've only ever been able to knock it out a few times until Quistis inevitably puts a million holes in it. That's a great cutscene, so I don't know if I want to take him down

Does anyone know what this changes when you come back to Dollet later? All I've heard is that it means the town doesn't get wrecked.
