Lost to the Ages: Looking back on the game "Myst" on its 20th anniversary

Use textual evidence ("they say") to answer the following questions:

• Which TV series is Myst compared to? How is it that Myst "irrevocably changed its medium?"
• Which other games dominated the adventure game genre in the 1990s? How did Myst compare?
• What is "the most important mark [Myst] made?" Why does the author claim that "without Myst, there's no Grand Theft Auto V or Assassin's Creed?"
• How did the creators respond to the questions about demographics? For whom did the Millers create Myst?
• Can the medium (video games) support stories and characters in the same way that a film or novel does?
• Why have multi-player shooters like Halo and Half-Life become "king?"
• What is the role of "truth" in art? Why are open-world games so popular today?

Bonus question: Which game overtook Myst as the number one selling game of all time? 

As far as length goes, I'm just looking to see that you've been thoughtful with your answers, have answered them with integrity, and have used evidence from the text to answer.

Happy thinking!
