Deponia takes place in a future where the world is overrun by trash and society is divided into two groups, those that live in the planet-wide junkyard, and those that live in the floating city above it. As a result of the trash-filled landscape, the game has an odd steampunk feel to it that puts a lot of the junk in the scenes to good use. Deponiaís character design, both the main characters like Rufus and Goal and the rest of the people, fit the visual theme nicely. Those that live in the junk tend to fit the steampunk design style rather well, while those from the floating city are dressed in a manner befitting a utopia as seen in some of our older science fiction movies.
Deponiaís audio also goes a long way to sell the mood of the game. This is mainly due to the dialogue and voice acting that seem to really fit the worlds the player will be discovering.
