# EcoQuest Series <small style="color: gray">Last updated: May 12, 2026</small> ## Overview The EcoQuest series is Sierra's two-game environmental-education adventure line: [[1991 - EcoQuest - The Search for Cetus|EcoQuest: The Search for Cetus]] (1991) and [[1993 - EcoQuest - Lost Secret of the Rainforest|EcoQuest 2: Lost Secret of the Rainforest]] (1993). Both titles star Adam, a young boy who is recruited by intelligent animal allies to solve ecological crises — the first game tackling marine pollution and overfishing in the world's oceans, the second focusing on rainforest deforestation and biodiversity loss in South America.[^ref-1][^ref-2] EcoQuest is notable as one of the earliest games to integrate environmental-education content into adventure-game design without sacrificing storytelling or puzzle quality. The first entry was designed by [[Jane Jensen]] (her Sierra debut, before *King's Quest VI* and *Gabriel Knight*) working with co-designer Gano Haine; the sequel was Haine's solo project.[^ref-3] ## Series Timeline | Year | Title | Designer(s) | Engine | Setting | |------|-------|-------------|--------|---------| | 1991 | [[1991 - EcoQuest - The Search for Cetus\|EcoQuest: The Search for Cetus]] | Jane Jensen, Gano Haine | SCI1.1 | Ocean (animals as allies) | | 1993 | [[1993 - EcoQuest - Lost Secret of the Rainforest\|EcoQuest 2: Lost Secret of the Rainforest]] | Gano Haine | SCI1.1 | South American rainforest | ## EcoQuest: The Search for Cetus (1991) Designed by Jane Jensen and Gano Haine — Jensen's first Sierra credit. Adam, the young protagonist, is recruited by a talking dolphin (Delphineus) to find Cetus, the lost king of the whales. The game takes Adam through a polluted ocean to talk to sea creatures, solve marine puzzles, and confront the human-caused causes of ecological destruction (oil spills, plastic pollution, illegal whaling).[^ref-4] **Design innovations:** - **Educational facts woven into gameplay** — interacting with marine animals revealed real biology and conservation facts. - **Anthropomorphic animal allies** — Adam talks with dolphins, octopuses, sea turtles using a "translator" device. - **Multiple solutions to puzzles** — emphasizing the value of non-violent problem-solving. - **Pacifist scoring** — actions that helped wildlife scored higher than confrontation.[^ref-5] **Reception:** Generally positive critical reception with multiple "Best Educational Game" award nominations. Found a devoted audience in the educational-software market that overlapped with the *Mixed-Up Mother Goose* and *Dr. Brain* audience.[^ref-6] ## EcoQuest 2: Lost Secret of the Rainforest (1993) Gano Haine's solo design (Jensen was already on *King's Quest VI*). Adam travels to South America to visit his father, an environmental researcher, and gets pulled into a quest to save the rainforest from logging operations. The game expands the original's animal-translator concept to include monkeys, jaguars, parrots, and indigenous fairy-tale animal-spirits.[^ref-7] **Design evolution:** - **Indigenous/folkloric framing** — drawing on real Amazonian folktales and conservation politics. - **Plant and ecosystem puzzles** — beyond animals, the player learned about specific plants' medicinal and ecological roles. - **Stronger antagonist focus** — illegal loggers and corporate land-grabbers as villains. **Reception:** Strong reviews; some critics felt the educational content was even better integrated than the first. Sold less than the original — likely a market fatigue issue rather than quality.[^ref-8] ## Series Design Identity What unifies both games: 1. **Adam as protagonist** — Young-boy hero with no special abilities, accompanied by animal allies who provide expertise. 2. **Environmental-education curriculum** — Real ecological facts integrated into puzzle structure. 3. **Animal-translator framing** — Both games used a device that let Adam talk with animals. 4. **Pacifist design ethos** — Conflicts solved through dialogue, cooperation, and ecological understanding rather than combat. 5. **Real-world social-issue framing** — The series didn't shy from naming pollution, overfishing, and deforestation as concrete villains. ## Legacy EcoQuest occupies an interesting niche in Sierra's catalog as one of the earliest "serious games" — titles designed to communicate real-world content (environmental science) alongside entertainment. The series's design influence is visible in: - **Later environmental-themed adventure games** — *Amber: Journeys Beyond* (1996), *In Memoriam* (2003), various indie titles. - **The "edutainment" genre** more broadly during 1992-1998 when Sierra, Knowledge Adventure, and Davidson & Associates dominated the educational-software market. - **Modern "games for impact" / serious-games movement** — academic studies of environmental gaming sometimes cite EcoQuest as a foundational example.[^ref-9] The series has not been revived. Both games are available on GOG.com as the EcoQuest Collection.[^ref-10] Jane Jensen's involvement in *EcoQuest 1* is sometimes overlooked in retrospectives of her career — *King's Quest VI* (1992) and *Gabriel Knight* (1993) tend to dominate her bibliography — but *EcoQuest* was the design credit that established her at Sierra and led to her larger flagship roles. ## See Also - [[Jane Jensen]] — *EcoQuest 1* co-designer; subsequent flagship designer - [[Gano Haine]] — Series co-designer - [[Sierra On-Line]] — Publisher / developer - [[Reference/Engine History|Engine History]] — SCI1.1 era ## References [^ref-1]: [Wikipedia — EcoQuest: The Search for Cetus](https://en.wikipedia.org/wiki/EcoQuest:_The_Search_for_Cetus) — Founding entry [^ref-2]: [Wikipedia — EcoQuest 2: Lost Secret of the Rainforest](https://en.wikipedia.org/wiki/EcoQuest_II:_Lost_Secret_of_the_Rainforest) — Sequel [^ref-3]: [MobyGames — Jane Jensen credits](https://www.mobygames.com/person/jane-jensen/) — Designer career [^ref-4]: [Adventure Classic Gaming — EcoQuest review](http://www.adventureclassicgaming.com/index.php/site/reviews/ecoquest_the_search_for_cetus/) — Design analysis [^ref-5]: [Sierra Help — EcoQuest scoring](https://wiki.sierrahelp.com/index.php/EcoQuest) — Pacifist-scoring mechanic [^ref-6]: [Computer Gaming World Museum — EcoQuest review](http://www.cgwmuseum.org) — Contemporary review [^ref-7]: [Adventure Classic Gaming — EcoQuest 2 review](http://www.adventureclassicgaming.com/index.php/site/reviews/ecoquest_lost_secret_of_the_rainforest/) — Sequel analysis [^ref-8]: [Hardcore Gaming 101 — EcoQuest](http://www.hardcoregaming101.net/ecoquest/) — Series retrospective [^ref-9]: [Serious Games Society — Environmental gaming bibliography](https://seriousgamessociety.org) — Academic citations of EcoQuest [^ref-10]: [GOG.com — EcoQuest Collection](https://www.gog.com/en/game/ecoquest) — Current commercial availability [^ref-11]: [Sierra Chest — EcoQuest](https://www.sierrachest.com/index.php?a=games&fld=series&id=ecoquest) — Sierra Chest catalog [^ref-12]: [Jane Jensen interview — Adventure Game Hotspot](https://adventuregamehotspot.com/feature/jensen-interview) — Designer recollections [^ref-13]: [MobyGames — Gano Haine credits](https://www.mobygames.com/person/gano-haine/) — Co-designer career [^ref-14]: [PCGamingWiki — EcoQuest](https://www.pcgamingwiki.com/wiki/EcoQuest) — Technical reference [^ref-15]: [ScummVM Wiki — EcoQuest](https://wiki.scummvm.org/index.php?title=EcoQuest) — Modern preservation
