History VideoGame / Obduction

** The initial scenario, an alien vessel appearing from the sky and whisking the player off to a strange world, is remarkably similar to ''VideoGame/TheDig''.

** A late patch added two new areas to buff out the backstory. One of them is the "crash site" bar, where a swap sphere has brought in a one-seater plane [note]the source of the propeller-turned-lever on the sluice gate[/note]. The other one reveals how C.W.'s section is powered - [[spoiler:a swap sphere containing part of a ''nuclear submarine''.]]

An environmental AdventureGame from Cyan Worlds, Inc., their CreatorDrivenSuccessor to the ''VideoGame/{{Myst}}'' series.

* ApocalypticLog: Justified and lampshaded; everyone knew a battle was about to begin, and they left journals laying out in various places in case no one survived the conflict and someone came along later to wonder what had happened.

* KirksRock: There is a rock formation at Hunrath that closely resembles the original from Start Trek.

* TheLawfirmOfPunPunAndWordplay: In the gas station, there is an ad for the law offices of "Kenway, Bilhem & Bale" (as in "can we bill'em and bail").

* WhamShot: A late patch added two new areas to buff out the backstory. One of them is the "crash site" bar, where a swap sphere has brought in a one-seater plane. The other one reveals how C.W.'s section is powered - [[spoiler:a swap sphere containing part of a ''nuclear submarine''.]]

An environmental AdventureGame from Cyan Worlds, Inc., their SpiritualSuccessor to the ''VideoGame/{{Myst}}'' series.

* SpiritualSuccessor: To ''VideoGame/{{Myst}}''

* AnachronismStew: Justified - the seeds can abduct people across time as well as space, and the humans who populate Hunrath were taken in years between the 1870's and the 2040's (or more). Most of Hunrath's geography is a 19th-Century mining town, but it is cluttered with buildings and objects swapped in from different times and places.

** In a patch after the release of the game, an extra one of these was added to Maray. Before its addition, it was possible for the player to fluke their way through the Villein number panels controlling the bridges, but upon reaching the sign-in area, where use of a specific number is required, the game became UnwinnableByMistake as there was no longer a way to reach the tutorial sheets in Hunrath.

* FrickinLaserBeams: Despite having very different technologies in many ways, both the Mofang and Villeins have opted for highly-visible beams as their main weapons.

** Mofang is on a sand-blasted dead world; [[spoiler:if you go up to the highest point of the sphere, you can see devastated roads and buildings -- it's ''Earth'', and it's a ''big'' [[{{Foreshadowing}} hint]] that you ''don't'' want to go back there]].

* Foreshadowing: The power light for Soria/Mofang is broken in the Hunrath watch tower. [[spoiler:Soria as a viable sphere, except for the tree, does not exist anymore.]]

** The entrance to the vault, although at first inaccessible anyway, is hidden by [[spoiler:a door which the player opened from the other side, much like a trick they used in ''Riven''.]]

* WorldTree: Each of the four alien world spheres has a tree at the center. These are the sources for the seeds used to travel between spheres, and are connected to the spheres themselves and to each other. There's a theory in-universe that these and others are all connected to a single "mother" tree, but this is unsubstantiated.

* UnspecifiedApocalypse: As seen in the bad ending, [[spoiler: The earth has been roughed up pretty bad, but the cause isn't clear. All we know is earth isn't a viable long-term home, which is why the seeds picked us up in the first place.]]

* JustForPun: In the gas station, there is an ad for the law offices of "Kenway, Bilhem & Bale" (as in "can we bill'em and bail").

* AllUpToYou: Cecil depends on the player to do all the legwork of getting all the spheres connected again, but there are good reasons for this: first, he's lame and can't move well, and he needs to finish building his giant swapper to take Hunrath back to Earth [[spoiler: or so he thinks]]. And in a slight subversion, if you never connect his battery despite numerous reminders, he'll eventually do it himself.

** [[spoiler: The Mofang intended for a Societal Collapse or Societal Extinction for the other three races by sending massive bombs and smart bombs. It's averted; defector Mofang told the humans about it who prepared a backup plan, the Arai were able to cut a Mofang off before he was able to give the proper signal, and the Villein stored all the humans of Hunrath in pods in an underground vault. The whole thing still manages to enact Societal Disruption, given the three domes from Earth (Hunrath), Kaptar, and Maray were transported to a new world and they have to start over as the only ones from their races.]]
