Sierra is a video game company founded by Ken and Roberta Williams.
The company built it's reputation as a company for excellent graphic adventures beginning in the early 1980s, and continued until it was purchased by Vivendi Universal (now known as Vivendi SA) in the late 1990's. Sierra now only exists as a label - as the entire Sierra staff was layed off and the Sierra building was closed. It is doubtful that Vivendi will produce any more adventure games.
The adventure games created with Sierra's Adventure Game Interpreter (and it's predecessors) are implemented in ScummVM using the code base from the Sarien and TrollVM projects, with permission obtained from the original authors of those projects.
PreAGI
There were several games that used some parts of the AGI engine, before it was mature enough (see TrollVM):
- Dragon's Keep (1982)
- The Gelfling Adventure (1983)
- Troll's Tale (1983)
- Mickey's Space Adventure (1984)
- Winnie the Pooh in the Hundred Acre Wood (1984)
AGI
- King's Quest (1984)
- King's Quest II (1985)
- The Black Cauldron (1986)
- Donald Duck's Playground (1986)
- King's Quest III (1986)
- Space Quest (1986)
- Leisure Suit Larry (1987)
- Mixed-Up Mother Goose (1987)
- Police Quest (1987)
- Space Quest II (1987)
- Gold Rush (1988)
- King's Quest IV (1988)
- Manhunter (1988)
- Manhunter 2 (1989)
Starting in 1988, adventure game development switched to the more versatile SCI (Sierra's Creative Interpreter) engine. ScummVM does not support these games.
