EcoQuest Series

Last updated: May 12, 2026

Overview

The EcoQuest series is Sierra’s two-game environmental-education adventure line: EcoQuest: The Search for Cetus (1991) and 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.12

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.3

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).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.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.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.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.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.9

The series has not been revived. Both games are available on GOG.com as the EcoQuest Collection.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.
