But, regardless, it's a fun game series.
At the end of Twilight Princess, the lead villain lies in a dark pool of his own blood, impaled through the chest with the master sword. He also sees his second in command snap his own neck in suicide. But that it the worst that Zelda ever gets, as far as I have seen, and the only time I ever saw blood. Otherwise enemies just explode into fairy dust. Plus, how is one supposed to see gore in the 8-bit games?
