History VideoGame / SevenTheDaysLongGone

* LostTechnology: In a manner similar to {{Literature/RoadsidePicnic}} most artifacts were garbage to the Ancients but are borderline (or outright) magical to the current world. That means when you find something the Ancients actually valued, it often has world changing potential.

* BlackAndGreyMorality: while good people exist in the setting, the main plot and many of the side-quests are definitely this. Teriel is an enthusiastic thief who has few-to-none reservations about killing if it means getting a heist done. The people he’s up against are definitely worse.

* NoOSHACompliance: Even the wealthiest area of the city has spots with rickety metal grating floor next to a twenty-meter drop and no railing all over the place.

* CyberpunkWithAChanceOfRain: Wardens Hold has appropriately rainy weather most of the time. The opening level in th capital also has appropriate weather.

* ShoutOut: In the "Drowned Past" DLC you can find pieces of "Mysterious Hazard Armor" which both in appearance and description refer to ''VideoGame/HalfLife''. The same DLC also adds crowbars as a melee weapon, which also reference ''Half-Life'' in the item description.

* ElectronicEyes: Teriel's right eye is a glowing red one. It is even noted in-universe when someone is given a verbal description of him.

* UsedFuture: society is built upon collecting and using the garbage of the Days Long Gone.

* GamePlayAndStorySegregations: As noted below, all item descriptions are in-character observations from the demon inside Teriel. The descriptions do not change in any way for times when the demon is not present.

* GamePlayAndStorySegregations: As noted above, all item descriptions are in-character observations from the demon inside Teriel. The descriptions do not change in any way for times when the demon is not present.

* MythologyGag: At the end of the game in the Ark, there is an arcade machine for ''VideoGame/{{Kholat}}'', another game from the same developer.

* LemonyNarrator: Item descriptions are all but stated to be coming from the demon inside Teriel, and frequently include snarky observations.

* LayeredMetropolis: Wardens Hold, the capital of Peh, has four main layers. The Paladial manors (top), Paladial (middle), the Shallows (lower) and the crucible (lowest)

* WrongSideOfTheTracks: The slum of Lewmer is where people who couldn’t earn (or buy) a level 1 visa get trapped upon arrival at Peh. Your choices of livelyhood are to work yourself to the bone in the techrot infested mines, participate in the (legal) slave trade, or become a criminal. They can’t even scavenge in Lewmer, because everything worth scavenging is just on the other side of that Visa 1 gate. The second act of the game is largely spent trying to earn or find a way out.

* AdvancedAncientHumans: Humankind at its peak, called The Ancients, were capable of incredible feats of SufficientlyAdvancedTechnology, but are gone (or at least gone from Earth) by the time the story starts. It’s interesting to note that while no one disputes that the Ancients were just (enhanced) humans, their mindset daily worries, and abilities are so foreign to a person of Teriel’s time that they are spoken about like a completely separate species.

* InsufferableGenuis: Teriel has a reputation for being one, though the player can chose to play it up or downplay it based on dialogue choices. And he truly has the skills to back it up, as the only way to surprise mission control during the tutorial is to ''botch'' the mission; the assumption was that Teriel was going to pull off the heist flawlessly as usual.
