1. Create a more regulated and more user friendly online capability. And by regulate, I mean get rid of the people who use cheat devices to act like they are the best. Also give us the option to add friend if we ever meet in random. Or just add random for some. You don't realize how boring it was to not visit another town in Wild World because no one else had the game.
2. Stop asking third party developers to make poor quality games that everyone who owns a Wii probably already has in some way, shape, or form. We already have Wii Fit, Wii Play, and Wii Sports, stop making shitty ripoffs and try to be creative.
3. Stop making the only motion you can do in most games is waggle.
4. Spend more time making quality 1st and 2nd party gmaes and less developing peripherals that work with about two games
5. As said above, make Wii Motion Plus free. It's like paying 50 bucks for a patch on a PC game. Why should people who expected accurate motion sensing from the start have to pay for it two and a half years later?
6. I'm probably asking too much, but give people the option to use a normal controller, like the classic or GC. I don't think people who are tired and want to unwind want to wave their arms around like an idiot.
7. Sell the demo mode patent, there are better ways to make games easiers for less skilled players.
8. Start a new IP that will attract all playeres
