Star Wars was originally released before there was a PG-13.Probably both answers are correct. George does have a lot of clout. But off the top of my head, I can remember 4 beheadings, two arms chopped off, a lightsaber through the thigh, and a lightsaber through the arm, a headbutt, and a big fight with Jango Fett. But, not a lot of blood was shown. Only a bit here and there. So who knows. AOTC probably just seemed less violent, and with all the other Star Wars films being rated PG, they though it was within the bounds of a PG.
