Players can purchase both the baseball and boxing additions for $9.99 each, or pay $1.99 to unlock all the games in Wii Sports Club for 24 hours. This special pricing plan makes it very affordable to enjoy the best version of Wii Sports yet (compared to the original Wii Sports and Wii Sports Resort). The addition of state / regional clubs, online play and HD graphics make Wii Sports Club a very fun experience, one that hardcore gamers can enjoy. With the addition of baseball and boxing, Wii Sports Club now has all the original games that we’re included in the original Wii Sports.
