Dies Irae: Getting Started

>What is this?
Dies Irae is a Visual Novel written by Masada Takashi and published by Light. It is the largest title in the Shinza Banshou setting, and the main work that Dies Irae Pantheon will be based on. There is also an Anime adaptation, however it is poorly done and only recommended to watch after finishing the VN.

>What order to play the game
While the routes are unlocked, and can theoretically be played in any order, it is HEAVILY reccomended to play Kasumi>Kei>Marie>Rei as the route build on each-other and the latter routes require information from previous routes to understand. https://gareblogs.wordpress.com/2017/06/01/dies-irae-amantes-amentes-english-walkthrough/ is a spoiler free guide.

>Amantes Amantes or Acta est Fabula
The AA version is the definitive and complete version of Dies Irae, and includes extra side stories and an extra ending and scene for the final route. Acta est Fabula lacks these additions but is uncensored, with H-scenes and a few other CGs remaining unchanged, as well as featuring uncropped CGs. The recommended way to play is to play through AA, and skip through AeF to unlock the H-scenes in the scene library OR to play through AA and skip through to unlock the other stories and read the extra scenes if the cropped CGs or lack of H-scenes are a dealbreaker.

>Other Titles
The other titles in the Shinza Banshou setting are Interview with Kaziklu Bey (A direct prequel), Paridise Lost (An indirect prequel disconnected from the events of DI) and KKK (A sequel). Currently they are all untranslated.
