Developers make this mistake too. In fact that's the reason anyone differentiates between non-games or games. Compromising the game for the sake of non-gamers has always been the issue. You're right in that non-gamers or casuals don't necessarily dislike depth or story. But companies like Nintendo so often assume they do. They shouldn't feel the need to do that.
So it pretty much becomes this
hardcore/traditional games: games like all games were prior to the DS
non-games: games made in the post-DS game industry that are clearly designed for casuals and non-gamers and intentionally lack depth
And I guess I would have a category called crappy games that consists of crappy games. Who cares about the details for those games? 
I don't think that is a fair accusation against Nintendo. I have always felt that within Nintendo's key franchises they have married the ability to appeal to casual gamers and traditional gamers. Look at Mario Galaxy, Wario Ware: Smooth Moves, Super Mario Strikers, Phantom Hourglass, even some of the nongames like Brain Age 2. There are elements that appeal to both markets. Part of that is art style and making the game graphically appeal to a larger audience. That is why I laugh when people believe Nintendo's art direction hurts them, it helps them more than it hurts them, because their art style is very disarming. Wind Waker is a perfect example, the art is very approachable and people that aren't gamers are willing to try it. Same with Wii Sports, which does have alot of depth for the traditional gamer as well.

I really disagree, because Nights is a traditional game that really has a hardcore cult following. Zack and Wiki from what I understand is a point and click adventure that is very challenging, not to mention the fact that Point and Click adventures are anything BUT casual experiences.
I don't believe that a hardcore cult following means that games a game is traditional and hardcore. Look at the design of Nights, it is a very simplified racing game where you gracefully fly around a world completing laps forth rings. That is not to say the game doesn't have depth...but it is to say that the game is very approachable to all types of gamers. A nongamer game or a casual game is one that is instantly pickable, and you are able to play the game immediately and have fun. That is what casual gamers want, it does matter if that game has no depth and is just fun. Or has tons of depth wrapped around a simple idea.
Oh, and I 100% completely disagree with you about Point and Click adventures not being casual...in fact they are the DEFINITION OF CASUAL GAMES, and are supported greatly by the casual market. Myst, The 12th Guest, and all those Point and Click puzzle adventures became hugely successful PC games, because they appealed not to the hardcore gamer, but to the casual market. My wife and her mom have played Myst 2 before I knew them and influenced them to play games. Point and Click adventures can be challenging, but usually they control in such a manner that anyone sit down and play the game.
