The book by Roger Caillois, Les jeux et les hommes, doesn't end to show its importance, revealing a new way of considering play and game in human culture. It is a pleasure to reopen it and verify that the four categories Caillois proposed to study the games: agon-competion; alea-chance; mimicry-role playing and ilynx-vertigo are more and more useful to understand a lot of present experiences.
