Got it!
1)
Across the archipelago. The 9th Hole in golf is on a small one.
2)
You know you don't have to look at the camera every time you do that? Whenever an outfielder catches a ball, they turn and stare straight at the camera.
3)
Swinging for two. In tennis, you're usually controlling both members of a doubles team.
4)
Well that made me break a sweat. Boxing is easily the most physically taxing option.
5)
Atmosphere so perfect you can feel the late nights and greasy food. From the music to the sound effects to the layout, Nintendo nailed the feel of a bowling alley.
6)
No arms? No legs? No problem! Miis have no representation of their arms or legs.
7)
Even grandma loves it! The game, especially bowling, was intensely popular among the elderly.
8)
Hey man, Nice Shot! One of the announcer calls in golf.
9)
Hey man, Nice On! Another such call.
10)
Motion controls that actually work! Finally! Wii Sports was a showcase for actual user friendly (at the time) motion controls.
