Freeseus, sorry to have made you confused.
Yes, Wii Fitness is another version of Wii Fit, but for European Countries, as mentioned by GreenSpoon and Game_boy.
I really like this game, as it is enjoyable and good to health.
The game is genuinely designed to help you keep fit.
The tasks are not set to be too easy so that you get not only the satisfaction and fun, but also exercises and consumption of excess energy.
One thing I wonder is that we may rather go to a gym regularly if we are so determined to keep fit.
I don't think I can improve my health without the endurance to play Wii Fit regularly.
However, with this endurance, I may get a more comprehensive training at a gym.
