Myst and Riven are two of my favorite games of all time. Give Myst another go if you’ve never finished it. After you complete the game, you unlock the “making of Myst” videos. The red and blue brothers in the videos are the two creators. They were independent developers in the 90s, so they made do with what they had. At one point they shove a rubber hose into a toilet to make the atmospheric bubbling sounds.
