One of the weirdest most boring concepts for a Wii game, is also one of the most fun games on the Wii. Easily.

I don't care what anyone says, this game is a pure stroke of genius. When you hear of a game where all you do is cook, and without even being able to get any food to eat in the process, you can't not feel a bit dubious. But after just a few recipes, this game becomes incredibly addictive.
Now, me and my friend are both incredibly hardcore gamers. We know what we like, and we love this game. It's so incredibly weird that its fun. Making a pizza with some incredibly heavy music blaring out from the nearby stereo is the greatest laugh we've had in absolutely ages. And there wasn't even any alcohol involved.
And, it's probably the most relaxed game I've ever played. The most stressful thing you come upon is failing to seperate an egg. And even then it doesn't really make much difference to the final product. Only to your score. A great way to calm down should you get slaughtered by everything site on Xbox Live, or on the latest installment in the Fire Emblem series.
