History VideoGame / EternalCity

* AnAdventurerIsYou: Wielders are sorted into six classes, the first three having melee range and the last being ranged: Warrior, Tank, Assassin, Mage, Shooter, and Support.
* AerithAndBob: The game's cast runs the gamut from the normal (ex. Ann, Bonnie, Rachel), to mythical (Askr, Sigrifa, Iscariot), and to foreign (Kaliyyeh, Sulette, Li Ruoyin).

* ApocalypseHow: Class 5, though the ranking can be lower depending on the ending. The default 'bad endings' where you fail leads to a world reset because it ends up getting doomed in some way with little variation in how it happened, but most often because the huge Black Gate that appears at the last day opens up to release an unstoppable horde of the Dimension's Monsters swarming the ends of the earth. Though the other failure endings unique to the route also lead to planet-wide destruction, ''even some of the 'good' endings'' end up becoming [[BittersweetEnding bittersweet]] because the world ended anyway while you and other died on your own terms.

** ''VideoGame/ExtraordinaryOnes'' feature a few Wielders from ''Eternal City'': Kun Yui, Viatin

* VisualNovel, in which you go about the city liberating zones to progress the current 'cycle', or in the case of 'routes', complete objectives related to the one you are on. Each cycle consists of seven days, and each day allows you twelve actions to perform [[note]]Every action progresses time by one hour, starting from 9:00 and sleeping at 21:00[[/note]], each requiring 10 Action Points (AP); [[AntiPoopSocking you have a maximum of 240 AP]], which restores at a natural rate of 24 hours, though excess AP can be converted into clocks that can be saved for later game sessions. As for the actual Visual Novel parts, a majority of the story is read this way, at times with {{Dialogue Tree}}s you can choose from--it must be noted that many of such choices have a major impact on the ending you want to pursue, so choose carefully.

The game takes place on a world similar to Earth, where an incident that would come to be known as the "Black Gate Event" endangered the entire world where monsters of the unknown, alien Dimension invaded through space-tearing Black Gates. They terrorized the people until they were pushed back to the Gates' point of origin by the combined forces of countries around the world, and people who suddenly gained powers after coming into contact with strange items--[[ArtifactOfPower Artifacts]]--from the Dimension, later termed "Artifact Wielders". Once the threat was suppressed, it was at that conjunction between the world and the Dimension where the [[CityOfAdventure city of Confluence]] was established, led by the Central Department that took up the responsibility of managing Wielders and stemming the flow of monsters still coming through the Black Gates.

Six months later, Confluence is in the middle of a city-wide battle between the monsters and the Wielders, with you as a "Commander" directing a time-manipulating Wielder named Ann to seal a massive Black Gate, [[UncertainDoom only for it to engulf the entire city along with yourself...]]

And then you wake up in a hospital bed to two women watching over you: Ann and Antoneva (the brunette woman from the battle you were in), suddenly acting like they never met you before. You cry all of a sudden, find yourself with [[IdentityAmnesia no memory]], and only a mysterious device called a Tactical Terminal with your name on it by your side.

* AnimeThemeSong: ''[[https://youtu.be/ts91a-3gP2g My Days]]'' is the game's opening theme (full version [[https://youtu.be/fW1HeyEQ8bM here]]) by [=GARNiDELiA=] (sung by Konomi Suzuki). Later, there's ''[[https://youtu.be/SjZl-_xyp5c Reminisce Reincarnation]]'' by Music/MythAndRoid.

** You can pit Wielders [[MirrorMatch against their own selves]] in stages where they appear as enemies, and routes involving them.
*** While the ''Steps Toward the Abyss'' route subverts it by ensuring that [[spoiler:you won't face Wielders loyal to you once the Central Department comes for you after defecting to Hiro, it's pretty funny to imagine that the remaining leaders (Antoneva, Anka and Elusha) are still playable and loyal despite their canonical selves opposing.]]

** No matter the cycle, [[spoiler:Antoneva will always die early before the last day even happens, most often to Mortification. Not even her focus chapter's endings allow it; it isn't clear if she still lives in ''Person in the Shadows'', and despite being cured of Mortification, she sacrifices herself in ''Deep Blue Star''.]]

* VisualNovel, in which you go about the city liberating zones to progress the current cycle, or in the case of 'routes', complete objectives related to the one you are on. Each action (used for district liberations and patrols) requires 10 Action Points (AP); [[AntiPoopSocking you have a maximum of 240 AP]], which restores at a natural rate of 24 hours, though excess AP can be converted into clocks that can be saved for later game sessions. As for the actual Visual Novel parts, a majority of the story is read this way, at times with {{Dialogue Tree}}s you can choose from--it must be noted that many of such choices have a major impact on the ending you want to pursue, so choose carefully.

** The ending song for ''[[https://youtu.be/30nyrZNpfBE Pure White Relief]]'' is based on [[Music/WolfgangAmadeusMozart Mozart's]] ''Requiem''.

** Some aspects of the game's setting are given a [[{{Deconstruction}} deep lookover]], and may or may not turn out [[{{Reconstruction}} for the better]], coming off as a DeconReconSwitch of the superhero genre. Issues include how a Wielder's powers affect their surroundings--and their own life--for good or bad or in-between, public fears (which are sometimes justified) of said Wielders using their powers for ill intentions, and a Wielder's life outside of being one.

* TwoRoadsBeforeYou: With a few rare exceptions, each route has a major milestone where it offers you two choices, and thus two paths to go down. This becomes the norm in later routes after ''Mirrored Shadow of the Transient World'', [[spoiler:possibly as a result of the two Antonevas tying together your possibilities.]]

** Invoked when using Wielders who have died in the route you're on. In the event of their death, disability or whatnot in-story, [[AntiFrustrationFeatures they can still be deployed in-game]], but their LoyaltyMission will be locked until you end the current cycle.

* StandardSuperheroSetting: The game ticks off a few checkboxes:

** The ending song for ''Pure White Relief'' is based on [[Music/WolfgangAmadeusMozart Mozart's]] ''Requiem''.

** There's a [[FantasyKitchenSink huge mix of cultures, settings and powers]].
