Yes. Experiment. But when something fails, you throw it aside. It's how evolution works. If an organism evolves a negative trait, it dies. Eventually, people will see how negative of a trait these things are, and kill them. Most of the people I know and like already dislike the Wii. Most of the people I know and like are gamers. Gamers are the only ones that are going to be willing to spend the enormous amounts of money that game systems are starting to cost. Eventually, game developers will realize that they need to stop trying to make everyone like games (which is impossible), and start focusing on those of us that already do.
All evidence points to the contrary. The system is selling well, the market has expanded and Metroid Prime 3's review scroes by "gamers" are currently on par with Halo 3.
How on earth do you get the impression it fails? Maybe if you talk to people like yourself, you can get that impression, sure. But I don't think people like you speak for the majority of gaming consumers.
