20. The computer-readable non-transitory medium storing the program according to claim 19 , wherein the judgment involves judging whether there is commonality on the basis of a first evaluation value that is based on the moving velocity of the specific character and the moving velocity of the non-specific characters of which moving directions are similar to that of the specific character, and a second evaluation value that is based on the moving velocity of the non-specific characters of which moving directions are not similar to that of the specific character.
19. A computer-readable non-transitory medium storing a program for causing a computer to execute: performing game processing including movement of a plurality of characters in a virtual world; specifying one character out of the plurality of characters as a specific character, on the basis of predetermined conditions; making a judgment of whether there is commonality in movement of a plurality of non-specific characters, which are the plurality of characters other than the specific character; making a determination of the specific character as a preferential display character if the judgment does not judge that there is commonality, and determines at least one of the non-specific characters as a preferential display character if the judgment judges that there is commonality; making an adjustment of drawing related parameters so that at least the preferential display character out of the plurality of characters is located in a predetermined area of a display image; wherein the judgment involves judging whether there is the commonality on the basis of moving directions among the non-specific characters of which moving directions are not similar to that of the specific character; and the judgment involves judging whether there is commonality on the basis of moving velocity of the specific character and moving velocity of the non-specific characters.
