Got my wii on Christmas day and I have found out this:
Super monkey ball is fun in the main game but most of the party games just aren't that well thought out. The graphics and music are good though.
It would be a crime to own a wii and not zelda - I'm five hours in and loving it.
Wii sports is great for multiplayer and is loads of fun at first but you will grow tired of it after a couple of weeks.
Wii play is great as a bonus for getting a wiimote and if you want to get one then I would definitely recommend getting it with wii play. Just don't buy wii play on it's own.
Red Steel's graphics would have been shockingly bad on the gamecube, let alone the wii. The clunky controls don't help and although I haven't played much of the game I can safely say that it deserved its 5.5.
