Prologue.
Dutch historian Johan Huizinga (1872-1945) released "The Autumn of the Middle Ages" in 1919, offering profound insights into the medieval era and shedding light on its dark times. With a deep understanding of language, Huizinga becomes captivated by play and devotes himself to the study of games within the course of history. The medieval period is a beautiful sunset that occurs as darkness descends, symbolized by sunsets and moonlight. Culture emerges from play as a bud of the Renaissance. The ideal life rooted in the era of the red dusk consists of three paths. Firstly, it involves escaping from the mundane world, denying worldly pleasures absolutely. Secondly, it involves striving to change the world, ardently desiring a transformed society. Thirdly, it involves filling life with fantasy, living life as a game. The paths of escape and struggle are taken by a tiny minority, while fantasy is a journey that many can embark upon. The quality of fantasy is determined by accumulated knowledge and intellectual abilities. When the realm of fantasy is beneficial and enjoyable, it truly becomes genuine play. By doing something beneficial for oneself and others, one gains wealth and prosperity.
