I hope Nintendo has brought in some new blood in their marketing dept.
What they have to do to sell Wii to all the markets they want to will be difficult. They are trying to take a product that is viewed so many different ways by so many different groups and sell it to all of them. Core gamers think nintendo=kiddy games (with the occasional worth-while title), adults and seniors think nintendo=brain-rot-box/time-sink.
It's going to be difficult selling it to the core gamers without totally alienating the adults and seniors, and vice-versa.
I think the BEST way to sell Wii is atually to downplay the game content and play up the game-play. Remember the first video that was released? Didn't show a single screen, just the gamers, young and old alike. I'm not suggesting that they don't show any game content at all, obviously, but if they really want it to be generationally universal, they need to sell it like any other generationally universal product.
Let's look at another product that plays media -- the iPod. What do the ads focus on? Design, the physical design of the product. The music is in the background and they have many ads with a variety of music styles. The iPod has become an icon because of its design. So much so that all you need is to see the earbuds to recognize the product. The Wii-mote has icon potential. They need to use that. Make people want one no matter what the content is. Then start showing some content, and making every ad span the full gamut of content, showing the core gamer stuff as well as the casual stuff as well as the mind enriching stuff.
I can see a tv ad that goes something like this: Attractive woman walking down the street, stops, notices wii-mote on pavement. Picks it up examines it (close-ups galore), presses the power button, is enthralled by what happens and how the thing works. She runs to someone else, a young kid, say, and the kid marvels at the design of the thing, then has a blast playing with it too, then he gives it to his older brother, who plays something hardcore, and then has a bunch of teenage friends over, and they all play something that looks fun. Grandma and Grandpa come in and start playing too.
Key: each transition from person to person will hilight the design of the wii-mote. Also, the crossing from teenager, to group of teens to teens with seniors will display to core gamers that their needs will be satisfied, plus they'll have something to do with girls when they get together (important), plus this is a console that gran and gramps will approve of, and so mom and dad will be cool with it too.
