A game is provided based on real data which changes with time reflecting
phenomena occurring in real life. In a game system 10 for providing a
virtual stock trade game to players base on the real life stock price
data, stock price data is obtained in almost real time from a broker etc.,
and stock virtually owned by the player in a game space corresponding to
real life is evaluated by the stock price data. By allowing the players to
compete for a time period until a target total asset value is achieved, a
new player can compete under almost the same circumstances as the
preceding players regardless of the timing at which they started
participating in the game.
