An idea I love for linking your "WiiWorld" to interactive games and the Shopping Channel, Voting Channel, etc.:
Working with Wii Sports 2, put a bowling alley, golf club, tennis court, boxing arena, and baseball staduim in the "WiiWorld". When a player's Mii walks through the door/gate to the location, the system will (quickly) load the specific sport (be it bowling, golf, wherever you are) from the Wii Sports 2 disc in the drive. When the player is done with the game, the system leaves the disc data stuff and you see the Mii outside that sport's building. All seamlessly. Playing the sports with your friends online. For the Shopping Channel, have a video game store (sponsored by/advertised as Gamestop, I'd expect) that connects to your systems Shopping Channel the same way. Pretty much the same thing for the voting channel and whatever else the Wii has online. (I don't know much about all the channels, I'm stuck on dial-up.)
Yay or nay?
