EDIT: There are a few games that require Wiimotes - Wii Party U and Wii Sports Club. The latter requires Wiimote+.
If you want to make use of backwards compatibility (if you want to play 'Wii' games), then you'll need a Wiimote and nunchuck.
Not fussed on the party or sports stuff but I might be interested in getting some Wii games that I missed out on like SMG1+2 and Xenoblade. If I get a Wiimote+ and a nunchuck am I good to go?
