Is it possible to play Mario Party 6 and 7 without the microphone? They're the only two Mario Party games I don't have yet, and I've really been wanting them. I don't want them if the microphone is required in order to play though.
Yes. It's possible to play them without the mic. Both parties have their own Mic Mode that solely uses the Mic. It's not required to play them. However, you can still change control settings in the Options to play Mic Mode without the mic.
also, in mario party 7, you can change it in the options to use your controller. i, personally, don't like using the mic, so i just use the controller (only for the mic mini-games with toadsworth though)
