of course, I got my wii since the launch and wii sports comes with the console

and no, not "very" limited. wii sports is limited too, but it got more games in one.
but in sonic, for example, you tilt the remote to move left and right, press the 2 button for jump, press the one button to slow down, flip the wiimote to the back to run backwards, move it quickly forward, while sonic is in the air, for a dash, shake the wiimote just before the countdown hits 1 to do a speed dash etc.
oh and to fly in a flying pot you have to pull the wiimote quickly up and down and while that, you can tilt it to move the pot etc.

just the first hour of the game is very fruststrating. sonic have to level up before he can do ANYTHING... he can't run, he can't jump... he is so useless in the first hour
