Legend of King Arthur and Legend of Zelda

Thinking over what I know about King Arthur and the stories about him and what we all learned in class about him, I've noticed similarities with the Legend of Zelda.  The Legend of Zelda is basically a series of games made by Nintendo about this boy (named Link) who is a selfless, virtuous hero who in most game plots saves princess Zelda, the people of Hyrule (Zelda's castle) or some group of people.

Take a look at the intro video for my favorite Legend of Zelda game, Windwaker, that I put rto the left and you can see that there are some similarities between the boy hero Link and King Arthur.  The idea that a selfless, virtuous hero saves countless people for a cause assigned to him.  ANOTHER striking similarity is Arthur's sword excalibur and the Master Sword in the game.  Link goes into a castle to pull the master sword and only the true hero is able to pull it up from the stone inside a castle-King Arthur was the only one who was able to pull excalibur from the stone...IT'S JUST TOO SIMILAR!
I find that the legend of King Arthur has pieces that are mysterious to me (same with the Legend of Zelda); concrete details about his existence seem to be unknown or unreliable.  I think it's that aspect of legends that make them easy to believe in and glorify.  King Arthur seems to be seen almost like a god because of his selfless sacrifices and his origins are written about vaguely similar to writings about Jesus.

I'm branching off right a lot now so I think this is where I'll end my mini rant about King Arthur being similar to the Legend of Zelda and apparently Jesus.

Happy Sunday everyone!
