I can't say that I'll miss it much. There were plenty of great games on it, I'm just not a very big fan of motion gaming and most of the games that were released for the Wii overused it. This made them difficult or impossible for me to play due to my disability, Skyward Sword being the worst offender. I know they were trying to innovate with the controls, but they could have at least put consideration into adding other control methods for gamers with lack of mobility. All that aside, I'm still happy that I got to enjoy great games such as Super Mario Galaxy, Mario Kart, Brawl, Animal Crossing and many others.
I loved some of the games on it, I just think it relied on the motion control gimmick a little too much.
