This game has a bibliography in the ending credits. I think it is the first time I have seen something like this in a videogame. Pentiment is an aesthetic and philosophical journey through the first half of the XVI Century, in which we can observe the lives of different characters while history unravels and a mysterious killer takes his victims through the years. The plot is not only well grounded in history, but contains fantastic elements, too. It is not fantasy, but it's more similar to what Cvetan Todorov theorized in the seventies. Sometimes you have the feeling of weirdness, and the setting is totally eerie. In Pentiment, landscapes often seems to hide something from our eyes and religion looks like magic, in opposition to the new technology of printed books. Still, it is not fantasy, but it looks like a ghost story. It's hard to choose a genre in which Pentiment really fits. History novel? Detective story? Ghost story? Fantasy? All and none of that. It Is, by far, one of the best written games I have ever played and one of the few games that, in recent years, tried to tell something interesting and new through the language of videogames.
