Character data including an image generation program, image data, a sound
program, and sound data, which are previously determined for each of characters
used in a game, is stored in a game device 10. A controller 12 having
a built-in tilt sensor 12c is connected to the game device, and operated
by a player performing a tilt operation. The image generation program and the sound
program concurrently process the image data and the sound data, respectively, using
the same tilt data output from the tilt sensor. As a result, an image and sound
of the character are concurrently changed in accordance with the tilt operation
of the controller. Thus, it is possible to provide the game device enhancing the
realism and the staging effects of the game.
