Warned. Bleach Blade of Fate doesn't have anything microphone featured, unless you're talking about wifi, in that case I wouldn't know. Phantom Hourglass only has a few, shouting to wake people etc.
Sometimes in Cooking Mama 2 you have to blow on the food,using the mic. Jump!Ultimate Stars also uses the mic,talking to people,but you need to turn it on and its for wi-fi. In Mario and Sonic at the Olypmic games you use the mic on this one event,you clap into the mic.
guitar hero on tour when you want to use that special power thing [the multiplier boost] you shout you can use a button to activate it but it motivates you to shout. it's also a lot easier to shout rather then pressing the button as there are times where it's going too fast and you don't have the time to move your hand from the touch screen to the button. deep labryinth uses the mic. sometimes you approach a tomb stone or something and you'll be asked to blow in the mic or to shout at the mic to shake or dust off things.
