Sierra
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. The adventure games created with Sierra's Creative Interpreter are implemented in ScummVM using the code base from the FreeSCI project. All of them were done with permission obtained from the original authors of those projects.
