Hakuoki

Hakuoki's gameplay requires little interaction from the player as most of the game's duration is spent on reading the text that appears, representing either dialogue between the characters, narration, or the inner thoughts of the protagonist. Often, players will come be given the chance to choose from options displayed on the screen that would be crucial to the story. The time between these decision points is variable and during these times, gameplay pauses until a choice is made that furthers the plot in a specific direction. There are six main plot lines that the players will have the chance to experience, one for each of the heroes in the story. When interacting with the chosen heroes with the routes, an "affection meter" is created which is raised by giving them an answer that pleases them. The ending the player will get in each route depends on the affection the player has achieved.

It also included all the basic functions such as CG Gallery, Music List, Scene Recollection, and skip options. Once completing a route, player can unlock the ‘Record of Service’ to select exactly which chapter they would like to start the next play through on, as well as adjusting the bachelor's affection level to access the different endings. There's also encyclopaedia in understanding the historical terminology and timeline.

In the updated remake Kyoto Winds and Edo Blossoms, six more routes are added. In Edo Blossoms, there's also "corruption meter", which tells the players the bachelor's corruption rate after becoming a Fury. Making sure the corruption level is low is crucial to prevent the player from reaching bad ends.
