Nintendo has introduced a whole slew of games for its Wii console at E3, with Wii Fit asthe flagship title. By the end of 2007, Nintendo expects to add around 200 titles to its more than 150 games, many from outside publishers, and will include titles that can be downloaded forits virtual console. But the company hopes for great things from its Wii Fit game, in which players get to exercise the whole body, using the Wii Balance Board, or WBB, which transmitsinformation to the console. It will offer a variety of different exercise activities from yoga to push-ups, virtual hula hoops and stretching, all conducted by virtual instructors. It’sexactly the kind of thing to appeal to casual gamers, especially older ones, although Nintendo didn’t announce a release date for the game. Although expected to be the big one,it’s just one of a number of upcoming titles for the Wii. There will be four Mario Bros. titles, including “Mario Kart Wii” and “Super Mario Galaxy.” “Metroid Prime 3” will be added to the Metroid Prime series, and there are plenty of third-party titles from EA, Sega,Activision and Disney Interactive. One of the more interesting Wii additions will be the WiiZapper, due later this year. It fixes onto the Remote and Nunchuk to resemble a gun, to be used with several games including “Resident Evil: Umbrella Chronicles” and “GhostSquad.” “In less than eight months, Wii has proved itself the video game system for everyone, and we’re not letting up,2 said Nintendo of America president Reggie Fils-Aime.“We’re producing hit after hit after hit, supported by a long line of third-party publishers who have shifted their resources to help make Wii the most distinctive video game system inhistory.”
