So you can play/watch the remake for the story and not pay attention to things happening in the new dungeons, if you only want to know the story for the sequel. The game references the first game quite often in terms of story, so it is recommended to know the story first.

The extra stories are nice to know, but not needed for understanding of the sequel.

The entire alternative route to an extend, it is largely ignored, minus one character, which also plays an important role in the original story. The dungeons which story content you can safely ignore in the remake: Miyabi Hot Springs, Sun TempleĬharacters: Eiji and Ayana/Kuchinashi and Stork.

In other words 'The new characters and dungeons' on the Steam store page of the remake are not important to know at all. The sequel is only referencing events that happened in 'The Caligula Effect' not the extra content of 'The Caligula Effect: Overdose' (the remake) You don't need to strictly speaking, but you'll get spoiled by the events in numerous ways.
