One con about the Wii is the controller options, some games are just not made for the Wiimote with its features, I think developers should have included an option in the games to either use the Wiimote with its motion, Classic controller or Gamecube controller, like Mortal Kombat does, this way some of the games will be so much better.
Just because the motion is there you shouldn't have to use it in every game released as I think it ruins some games.
