There are two Kevin Garnett entries that I stumbled upon... one is listing him as a character; the other is listing him as a person.
Not sure if you'd want to delete one, or combine the two somehow.
Edit: Tried to delete this after finding out it's been mentioned and addressed before, but the post still shows up :/.
If they are credited in a game they get a person page, if they are a character in a game then they get a character page. So people can have both a character and person pages.
The criteria for someone having a person page is they have to be credited in at least one game, meaning they need to appear in the end game credits. But they can also have a character page if they actually appear within a game.
