Wii Speak is very fun. You can download WiiSpeak Channel (one dowload per package) and talk to 3 friends at the same time.
I have 4 good friends that we chat in the Channel and in Animal Crossing and it's fantastic, the game becomes much more alive and fun!
The sound of it is similar to any open-speaker telephone. You hear any sound in the room. There is a slight delay sometimes but nothing to reduce the fun of it. The channel is also good - we use it to arrange a meeting with friends. At some point I had 3 friends in my home and we were speaking with other 5 friends (9 people total). It was confusing but very fun at the same time. The volume of your TV should not be too loud because you hear your voice after you finish the word you said. I recomend it - It's a great add on to the fun of gaming or just chatting with a friend without having the phone stuck to your ear. Definitely worths the pricetag.
