DS (6.5) is really keen to get a Wii - he started being helpful in August because he'd decided on his own that that was the way to get one for Christmas.
I don't know much about them - but if I do get one, do I need a Wii or a Wii U? And why is this one twice the price of this one? If I get the first, can I then buy older Wii games second hand for it? Or might I just as well, at that point, get a secondhand Wii?
Any advice gratefully received. Thanks in advance.
