If there is one hero, sometimes I will give him my first name, or his/her intended name if there is one. If there are multiple heroes and they have intended names, I use those, otherwise I usually use my name and my friends' names. In the case of OOT, which I've beaten 1,000,000 times over, sometimes for the heck of it I choose Zelda or Nabooru, just because of the conversations that take place with those characters later in the game. (They both treat their own names generically, like any other name.) If you name yourself Zelda, she says that the name is "somehow... familiar". And if you name yourself Nabooru, when you tell her your name, she asks, "What kind of a name is that?" Cheap thrills.
