         7 . A game device for proceeding a game by placing game objects related to the game in a three-dimensional virtual space and by controlling said objects, comprising: 
 first game proceeding means for proceeding the game by controlling said game objects in a first game field in said three-dimensional virtual space;    second game proceeding means for proceeding the game by controlling said game objects in a second game field in said three-dimensional virtual space;    cursor object forming means for forming a cursor object indicating a certain area of one of said first and second game fields as well as an area of the other game field corresponding to the certain area; and    perspective transformation display means for forming a screen picture by transforming the coordinates of each object including said cursor object within view of a viewpoint located in said three-dimensional virtual space.    
     
     
         8 . A game device according to  claim 7 , wherein said cursor object forming means forms said cursor object as a polyhedron with an area of said one game field as its top and with an area of said other game field as its bottom.  
     
     
         9 . A game device according to  claim 7 , wherein said cursor object forming means displays information on the side face of said cursor object.  
     
     
         10 . A game device according to  claim 7 , wherein said cursor object forming means sets display scales of the top and bottom of said cursor object, respectively corresponding to the display scales of said first and second game fields.  
     
     
         11 . A game device for proceeding a game in a game field formed in a three-dimensional virtual space, comprising: 
 cursor moving means for moving a cursor in said game field in accordance with operation;    viewpoint moving means for moving a viewpoint located in said three-dimensional virtual space in accordance with said cursor;    coordinate transforming means for transforming a view range of said viewpoint into a screen coordinate system; and    viewpoint position adjusting means for adjusting a position of said viewpoint so that a non-mapping area will not appear on the screen when said view range extends beyond a mapping area, in which a picture of said game field is drawn, to the non-mapping area.    
     
     
         12 . A game device according to  claim 11 , wherein said viewpoint position adjusting means adjusts the position of said viewpoint so that said cursor will be located at the center of said view range.  
     
     
         13 . A game device according to  claim 11 , wherein said viewpoint position adjusting means adjusts the position of said viewpoint on condition that said cursor has moved beyond said view range.
