If we get more Mii creation features, then it's ok. They really need to extend on the Mii pallete. I think Nintendo said something about making it more HD friendly next year.
A chat channel would help a lot. This is the problem with the US and Japan. The Japanese have a completely different idea on basic online features. In FF11 the Japanese were the most anti social people in the game. Unless you wrote Japanese they showed little to no interest. I credit the few Japanese that cared to chat, but overall they were very fickle, and it ruined the game when it came to getting groups the first year. Another example is Resident Evil Outbreak. It has no voice chat in a game that should.
