Pixar sneaks in content that entertains the adult demographic - moral lessons or something to think about. Up is a story about love and the stages of grief, for instance. Wall-E is both a story about the environment and a story about love transcending boundaries of class - Wall-E was a trashbot and Eva was a classy security bot. Pixar movies are cleverly made. Splatoon is about shooting each other with ink. Can we agree that the two are not on the same level? Also, I'm labeling this as a kids game because that's what it is. Anyone can play any games they like, there is nothing wrong in playing kids games, but that does not change the fact that they are kids games. There is nothing inheritently negative about this term, it's not ambiguous.I find there's a huge difference between "accessible to kids" and "accessible to everyone". Pixar movies, for example, are accessible to everyone. The smurfs movies are accessible to kids. I see Splatoon as falling in the pixar category rather than the smurfs category.
I don't really care who all can have fun with it, so long as I can have fun with it. Labeling it as a kiddy game would seem to put it outside of that "for everyone" realm I'm talking about.
