- Crowning Music of Awesome: Say what you will or won't about the variable quality of the games themselves, but the music in Sierra games (that came out once PC sound had evolved beyond boops and beeps) was consistently awesome.
- Cult Classic: Even the games that came out in the early eighties still have a strong following.
- Executive Meddling: What ultimately led to the company's virtual collapse after the 90s. After being purchased by Vivendi, the new executives closed Dynamix, (developer of the Aces series and other racing and combat simulations) and directed the company to abandon adventure game development entirely. Unfortunately, despite publishing a number non-adventure titles, this pretty much eliminated Sierra's main product as a developer, and the company never really recovered, until by the end of the 2000s Sierra effectively only existed as a label. Meddling immediately prior to the Vivendi buyout was also directly responsible for the utter mess that was King's Quest: Mask of Eternity, and the lukewarm reception for Quest for Glory V, among the last adventure titles produced by the company.
- Most Wonderful Sound: You know the one...
- Porting Disaster: Sierra is infamous among Amiga fans for the poor quality of its ports compared to the platform's abilities. The Amiga version of King's Quest VI: Heir Today, Gone Tomorrow is actually pretty well-regarded, though it was done by an outside company.
