WWT is a highly addictive game that is bound to keep your eyes glued to the screen. If it doesn't, then, well, I'm not quite sure what's wrong with you.
It doesn't quite measure up to the previous WarioWare games, but using the touchscreen to draw, drag and drop, or the microphone to blow as hard as you can, are things you couldn't do in the others.
It's great for playing in short bursts, or even a couple of hours if your eyes can take it. You can't help loving all of the minigames.
WWT won't take you long to complete, but it has a lot of replay value in it.
Just don't play it in public though – it'll make you look like a complete idiot.
