Abstract: A game apparatus provides gameplay concerning development of characters evolving through multiple evolution stages. Type information uniquely identifying the type and the evolution state of each character capable of being developed in the game apparatus is defined. The game apparatus includes a first acquisition unit acquiring information about a state of activity of a wearer; an update unit updating a first parameter and a second parameter concerning a developing character based on the information about the state of activity and the type information about the developing character; a display control unit causing a display unit to display the developing character in a display mode corresponding to the first and second parameters; an accumulation unit accumulating an evolution score concerning development of the developing character based on the first and second parameters; and a determination unit determining a target character of the developing character based on the evolution score.

Abstract: A game system includes a game apparatus providing gameplay concerning development of characters evolving through multiple evolution stages and an information communication terminal with the game apparatus, which causes a display unit to display an evolution flow indicating a group of characters. Type information uniquely identifying the type and the evolution state of each character is defined. The evolution flow is displayed in an aspect in which at least part of the characters is unidentifiable in an initial state and is configured so that the number of kinds of the characters in each evolution stage is identifiable. The information communication terminal includes a first acquisition unit acquiring the type information and a display control unit that changes the evolution flow including the character having the acquired type information from an unidentifiable aspect to an identifiable aspect to cause the display unit to display the evolution flow.
