Nintendo Power details the various control options in Grand Slam Tennis.
Nintendo Power recently shed some light on EA Sports Grand Slam Tennis. The game sports a unique art style that’s not quite the usual realistic style that people usually expect from an EA Sports title. It is also playable with or without Wii MotionPlus; without Wii MotionPlus the game is very responsive, however it won’t feature 1:1 movement. To pull off moves such as backspins, topspins, and other moves the player has to do the appropriate motions while holding a specific button.
With the addition of Wii MotionPlus you will see the characters mimic your hand movements in real time. For example, the game will know if you’re doing a backhand or a forehand swing, how high or low your tennis racket is, or if you are going to perform a topspin or backspin just based on your movements!
Grand Slam Tennis also gives you an option of playing with or without the Nunchuk. If you play with the Nunchuk, the analog stick will be used to move the characters manually. If you decide against using the Nunchuk, your character will move automatically towards the ball like in Wii Sports Tennis.
