As someone else said earlier: how long is a piece of string?
Any opinion given here is entirely subjective and really only reflects either the individual's opinion or his/her personal experience.
In my case, I bought the Wii for my wife because she thought the motion controls were cute. She lost interest after about two weeks.
It's not a console that my son or I use so it has been lying idle for a long time now. I freely admit though that it is very good at what it does...it is just not for me.
I would say its major success was due to a combination of marketing and motion controls. It attracted not only committed gamers who loved the Nintendo brand and game catalogue, it convinced many people who had never played computer games to jump in and try it. That is a good thing in my opinion and, consequently, I welcome its huge success.
As I said in the beginning though, that is just my opinion and no more.
