In its first year, the Wii has changed the video game landscape. It's brought people in who never thought they would care about video games. New methods of interacting with onscreen events have been invented. The image of the video game has started swinging away from the nerd-basement stereotype and toward a more family-friendly, even trendy experience.
But the Wii is still a game console, and it can't be completely different from every other console. It's a universal rule that all video game systems must be populated by a bunch of really terrible games, and the Wii has certainly done an admirable job of attracting cheaply-made, ill-conceived, untested, embarrassing garbage. It's really a mark of a system's popularity that so many publishers have come running with their shovels. It's a mark of the Wii's strength as a platform, as well, that it has managed to survive despite the existence of some of these games.
