Out of all visual novels, I would argue that fata is most akin to the Western Canon aka the "great classics" of literature (don quixote, shakepeare, edgar allen poe, dickens, etc.). It's a very, very, VERY difficult read, much more so than steins;gate or fate or clannad or any other highly rated visual novel. Part of it has to deal with the heavy philosophical undertones, multiple layers of narrative, and overall complex writing structure that the visual novel uses. Part of it is due to the heavy and serious topics the vn covers, as well as the complexity of the characters involved. No character is underdevelooped in this vn, in fact some may argue that characters are OVERdeveloped. Compared to any other vn, fata's characters (especially jacobo) feel a lot more "human" because of this extensive development.
