Well, I think we can define as an adult game any game that has a level of violence/nudity/whatever that isn't adequate to kids. We can define as an adult game too any game that has a more complex history that kids wouldn't enjoy. A kid's game is one that doesn't have any inadequate content and has a simpler history or isn't about a delicate and adult theme.
It's like comparing films. There are games that are like big drama films. They can contain some violent or sexual content and its history won't fit with children. I see most Nintendo games as Pixar movies. They are great and a lot of adults enjoy them, but they are primarily aimed at children.
