RetroGaming

As many have said, it's all about the games. How well the WiiMote functions in a game is largely dependent on the actual game as well. Nintendo pretty much showed the peak of what they can do with the Wii Sports games, and there are a few other games that use the motion controls well, but they tend to be the minority. That said, as a traditional controller it's not the worst thing in the world, and you can still use a Pro controller, the classic controller attachment or a GameCube controller for more traditional controls. The Wii library can be underrated due to the prevalence of shovelware, but there are great games like the Mario Galaxy games, Mario Kart Wii, the last good Mario Party before Superstars, the original versions of Twilight Princess and Skyward Sword, the aforementioned Wii Sports games, the second Mario Strikers, the best of the New Super Mario Bros games, Metroid Prime 3, Fire Emblem Path of Radiance/Radiant Dawn (if you can afford them), DKC Returns, Kirby's Return to Dreamland, Kirby's Epic Yarn (another game that used the motion controls well) and many more. (As an aside, I think the Wii U will also be known as a console with an under-rated library down the road.) Sadly, due to its perception and underpowered hardware for its generation, there's not much actually good third-party software for it, but Nintendo themselves supported the Wii more than adequately.
