Wii online WILL be free, it will be free to search the net using the Opera browser (free to download til June/July? next year after which you will have to pay ~$20 for it and standard net rates i.e. you paying for your internet connection as you would if you wanted to go on the net on your PC)Originally Posted by Homesrfan
WiiConnect24 will be free as well for updates, game demos etc. the Virtual Console will charge you to download retro games. That's it though, the game's will be free to play online to, after all you don't pay fees to play Mario Kart DS online do you or Metroid Hunters.
Can't be bothered to find sources etc other people can back me up if you need anything else.
