Depends on the game.
A lot of the games use the motion sensor, and some of them don't use it as much.
Some of them have options to change the control scheme (like Super Smash Bros Brawl will be able to use a bunch of different controles/controllers)
It honestly depends on the game, you'd have to search it up, but a lot of them do. A lot of the time though it's just flicking your wrist or something of the sort, nothing to strenuous. (Usually)
