I agree completely. The only reason I bought my wii is that I thought it would be much more fun to play than the other consoles. Even my wife loves it and she hates video games.
Nintendo has hit a home run and they know it. The data is proving it. Soon, all of the companies that weren't 'bothering' with porting their games to Nintendo consoles will be concentrating on them. The innovation that Nintendo is introducing will expand the bounderies of games as more and more game companies put their ingenuity to work.
If you have to pick between games that are more fun or more pretty, more fun wins most of the time. Pretty is cool, but it gets old. Fun never does.
