From the Nintendo Press release: “Wii Sports offers five distinct sports experiences (tennis, baseball, golf, bowling, and boxing), each using the Wii Remote to provide a natural, intuitive and realistic feel. Players can use their own Mii caricatures in the game and play them against their friends’ Miis for a more personalized experience. As players improve, their Miis’ skill levels will increase, so that they can see exactly how much better they’ve become.”
