As cool as the trailer was for them, I'v overall disappointed at the inclusion of Mii's. There are neat things, like the fighting style diversity, and I was expecting to be included in the game in some form.
Bad things however are that the fighting styles don't seem to have much inspiration from the games the Mii's have actually been in. There's some minor factors, but the fighting styles are all generic ones for the most part rather than Wii Sport, Nintendo Land, or Pilot Wings inspired. Furthermore the amount of effort put into making these characters and their large move-sets worries me. A lot of that effort could have gone into other characters. I guess this latter criticism will be null though provided the roster doesn't show how it's been affected by so much devotion to making many Mii move-sets.
