I sold the WiiSpeak because I don't need it... or didn't need it. The store I was at had only the bundles, so I bought one and sold the accessory. The only reason I got the game was because two of my friends had it and wanted me to get it, neither of whom have WiiSpeak. We just talk on the phone whilst we play.
But then, a couple people on another forum I visit bought the game, and when they found out I had it they kind of insisted that I play it with them. My friends aren't comfortable with the possibility of random people showing up when we play, so I created a second character to use for people on that forum.
If there are now people here on this forum who want to play, then I think I'll create a third character. It's a strange way to organize things I know, but that's the way I like to do it.
If anyone who plays with me wants to use WiiSpeak I don't mind, but it might be kind of awkward since I have to use the text chat.
