my understanding is that, unless otherwise stated, wii sports is the included game. Ours came with it and so did the one my brother got for Christmas. And the fact that all of our friends who also own a wii have that game, leads me to believe the game came with their machine.
The base package only comes with one controller and nunchuck thingy. We bought a second controller but not a second numchuck and find that, with the exception of boxing in wii sprorts, we don't need the other nunchaku.*
(*I have no clue how to spell that, so I used all three spellings in the wikipedia article.)
