9This book begins with a look behind the scenes of the development process and attempts, through a systematic comparison with the Souls series, to examine the evolution of FromSoftware's game philosophy. This is followed by a detailed analysis of the universe, the plot and the characters, as well as a study of the creators' artistic, cultural and historical influences. The last part deciphers the work through cross-cutting aspects, from its themes to its soundtrack, as well as the management and relevance of difficulty in video games.
