Here's what I would like to see:
- Weight Room
- Ice Hockey
- Horse Shoe
Online would be very simple, on the main menu, there is option that would say 'online'. You would be able to play against players currently online from around the world in the sports from Wii Sports & Wii Sports 2.
The wieght Room will be were you get fit. You can lift dumbells, rowing excersises, indoor biking, bicep curls and other things you would do to work out. This would make your Mii have more stamina when playing.
Ice Hockey - Wii Remote
Use the Wii Remote to take slapshots and pass. Hold it as you would a hockey stick.
Horse Shoe - Wii Remote
Use the Wii Remote to fling horseshoes at the post.
Swimming - Wii Remote/Nunchuck
Use the Wii Remote and Nunchuck to do strokes like Freestyle, Backstroke, Breaststroke and Butterfly.
Basketball - Wii Remote/Nunchuck
Use the Wii Remote and Nunchuck to bounce the ball and dribble it back and forth. Also take shots by waving the Wii Remote and Nunchuck as you would take a shot in Basketball.
Football - Wii Remote
Much like Madden, use the Wii Remote to pass the football.
