Abstract: A technique is disclosed that makes it possible to prevent or suppress various problems that may occur due to character placement control when implementing a multi-player game that utilizes an augmented reality space. A basic area is set based on the relative position of each game device with respect to an AR marker, and an element area is set so that the AR marker does not lie outside the imaging range of a CCD camera module of each game device. An overlapping area of the basic area and the element area is calculated to be a placement area. The motion of an attention object is controlled so that the attention object remains within the placement area.

Abstract: An information storage medium storing a program that generates an image of a virtual space viewed from a virtual camera, an operation object and a non-operation object being disposed in the virtual space.

Abstract: A game apparatus includes an LCD, and displayed on the LCD is a game screen including a display portion that displays a planar positional relationship between a player object and enemy objects present in a three-dimensional game space. The player object and enemy objects are flight objects, for example. Each time a player presses an X button, a selection state of an enemy object as a target of the player object is switched by turns according to priorities of the enemy objects. When the player continuously presses the X button over a certain period of time, regardless of the priorities of the enemy objects, the selection state is switched to that of a highest priority enemy object.

Abstract: A game apparatus includes an LCD. An on-earth object existing in a virtual game space is reproduced on the LCD from a viewpoint of capturing ahead of a flying object moving in the virtual game space. A velocity parameter and a direction parameter which defines the movement parameter of the flying object are changed in response to a button operation by a player. An altitude where the flying object will reach after a lapse of a time T (T>0) is predicted on the basis of the movement parameter of the flying object. A height above the sea level of the on-earth object existing in the predicted point is detected with reference to map data. Difference information indicating a difference between the detected height above the sea level of the on-earth object and altitude of the flying object is output to the player through the LCD.
