What then happened was a major overload of games, most of which were not worth buying, and consumers got feed up and simply stopped buying.
I got a Wii about two years ago, and haven't bothered to even browse the Wii section of games in stores in probably 1.5 years. It's basically just a convenient emulator as far as I'm concerned - it's simply not worth the bother of browsing through the gobs and gobs of utterly horrible movie-tie-in and mini-game shovelware to find the bare handful of games that are Wii exclusives and worth playing. I can understand trying to hit a broader / more casual market, but I don't think anybody can deny that the vast majority of Wii games are simply shit without crossing their fingers behind their back.
Nothing is finished until the paperwork is done.
