I generally, use my own name or Troii (character from ogre battle 64). I find the defualt name used in a lot of games is usually strange or just doesn't fit the character.
I always use the canon name unless it's like Pokemon or something. I use my own name in Pokemon. If there is no canon name then I will make one up or just rip one from a character I like.
If i really care about the story i'll use my own name,
but if its zelda, or Skyrim or something that i wonna play but wont pay too much attention to,
then i'll enter my name as "slippery dingus" or something like that.

If the character is actually a character, like Link, I will use Link. Other games that you have yout own character, I just think of a random name or a name that kinda matches the time of the game.
If I can customize my character, like hair, face, blah blah blah. I'll pick my own name. but its its got a main character with a name already decieded for them I'll use that.
If a character has a canon name, I use that. Other than that, I either use a game that fits to a character in a fantasy game (in, well, fantasy games) or use a name of the culture the character comes from (in games set in the "real world"). Sometimes, I use a name from an anime or another work, but that's rare nowadays.

I always use the character's name if they have one. If they don't then I'll usually just go with a random name I like. I often use Raiden for male characters ([size=10]not a Metal Gear reference, I just like the name in general[/h]). You should see how weeb all my Disgaea names are though.
