Just Ocarina of Time and the original NES release.

But that's enough to make me hardcore... right?... Guys? Am I right?!?!?!?

Yeah, Zelda might follow Star Wars in going from a PG rating to a PG-13, with Episode III (I think Episode III is PG-13, don't take that to the bank, though.)

I wouldn't be surprised if it ended up getting a T for violence.
