In versions 1.0 1.1 and 1.2, there was blood in there. For example, when Ganon and Ganondorf are slayed, they cough up red blood (except 1.2). When Link gets attacked, a red slosh comes out of him (could be a red flash or blood). Once Barnigade is defeated, he explodes in a bloody way. So, do you think OoT is the bloodiest E-rated game (1.0 1.1 1.2)?
