These two.
Kirby Air Ride is a multiplayer game and would have been better off if the gamecube's online function was more often used.
Shadow the Hedgehog had a different kind of control than other Sonic gamecube games because he shot a gun, and the controls were slippery in an effort to make his movement while shooting more realistic, but many people didn't like it.
They couldn't have done the shooting better for a Sonic game either and people don't understand that.
Some of the missions are frustrating, but the game can be completed without them.
It managed to be decent despite Sonic games changing their format and turning stale after this.
