Deponia

=== Setting ===
The game's story takes place on the planet of Deponia - a world which originally was inhabited by a large human population, until the majority ascended towards living in a utopia-styled floating city called Elysium. Over time, the Elysians forgot their origins and past with the planet, assuming it to be nothing more than an uninhabitable world. For the remaining humans left behind, their home planet became a dumping ground for those who ascended, leaving them to make settlements amongst the trash that is regularly dumped on the surface's landmasses, with communities managing to thrive as best they can, and clean water considered the most valuable commodity for them.

Story

Seeking to follow in his father's footsteps, Rufus, a young man living in the town of Kuvaq, constructs a makeshift rocket in his latest attempt to travel to Elysium. After a mishap causes the rocket to break up in mid-flight, Rufus manages to land on a cruiser run by the Organon - a militant organisation that terrorises the inhabitants of Deponia and regularly dumps trash on its surface with their craft. While aboard, he witnesses the Organon, led by Baliff Argus, pursue a young Elysium woman named Goal, who is shocked that they have been covering up the fact that Deponia is still inhabited by humans. Argus reveals to Goal he intends to keep her quiet and prevent her informing others of what she saw, forcing Rufus to try to rescue her. After managing to inadvertently knock both of them off the ship, Rufus discovers Goal was knocked unconscious when she landed in Kuvaq and that the town's residents seek to have the honour of looking after her.
Wishing to prevent this and complete his rescue, he begins working on a way to revive Goal, and does so through a specially-made coffee created from bizarre ingredients he collects around town. When she awakens, Goal is found to be unable to speak properly as a result of her brain implant - a cartridge based system which stores an Elsyian's memory, that was damaged in the fall - though Rufus learns that her fiancé, Cletus, will reward him handsomely for her return. Sabotaging the town's post office to use its radio, Rufus contacts Cletus, and upon convincing him to take him to Elysium in exchange for the return of Goal, agrees to bring her to the Lower Ascension Station beyond the town's borders. Shortly after he makes the arrangements, Argus arrives in Kuvaq to track down Goal, forcing Rufus to escape with her before they can abduct her.
After travelling for some time, Rufus reaches a garbage mine, and seeks out transportation that can bring him to his destination much quicker. After fixing up a garbage mine bike with the help of Doc, a travelling maintenance man, Rufus continues on his journey, and eventually reaches the Lower Ascension Station with Goal. Leaving her to rest, Rufus seeks a way up to the station's platform at the top. After reprogramming a lift to take him up there, he soon finds that the Organnon have arrived at the station, along with Cletus. Listening in on his conversation with Argus, Rufus overhears them plotting together to prepare for Deponia's destruction with the Organnon's leader, Prime Controller Ulysses, and that Goal is only needed for the codes needed to ascend back to Elysium stored, within her malfunctioning brain implant; once acquired, Cletus intends to wipe her memory, so she has no recollection of encountering life on the planet.
Seeking to prevent this, Rufus soon finds Goal missing, but follows a trail leading him to trawler vessel owned by Captain Bozo, in which he receives assistance once again from Doc. After fixing her implants, Goal awakens and is brought up to date by Rufus. Returning to the Station, the pair encounter Cletus, who tricks Goal into distrusting Rufus and forcing him to switch her memory cartridge for a back-up he had brought along. Ascending to Elysium but guilt-ridden by what he is doing, Rufus comes clean to Goal about the change of cartridges and returns to the planet to retrieve her memory cartridge at her request. Although Rufus retrieves it, he encounters Cletus and Argus, who force him to hand back the memory cartridge. While Cletus ascends back to Elysium with Goal, Argus prepares to deal with Rufus, who knows too much about their plans. However, Rufus refuses to hand back the back-up cartridge he still has, and manages to escape using Ulysses' flying communicator system. In the aftermath, Rufus decides to travel with Captain Bozo, but remains quiet on what he knows of Deponia's future.
