Wii buyers who skipped getting a Gamecube might have a hankering to play the games they never could before (Super Smash Bros. Melee!). Having a Wavebird controller is probably one of the best accessories to get for the Wii, due to its extreme compatibility with non-Wii games and ridiculously long battery life. For a controller that is a jack-of-all-trades on the Wii, it's kinda sad that you can't navigate the Wii menu with it. Heck, you can't even get past the "WARNING-HEALTH AND SAFETY" screen with the Wavebird. When you put in a Gamecube game, you have to find your Wii-mote to activate the game from the main menu. It's a little thing that would be a nice simple fix in a future update. There is still much Super Smash Bros. Melee to be had and using the Wavebird to navigate and shop on the Wii menu would be nice.
