I felt both nostalgic and excited about the prospect when i came across a Kickstarter for Cyan to develop a new computer game in the spirit of Myst that leverages modern technology. They call the game Obduction and have a teaser at the beginning of the Kickstarter video.
The developers at Cyan did great work with both Myst and Riven. The Unreal 4 engine has the power to do something cool, but I do wonder how removing the movement restriction provided by a static-image puzzle will impact the experience. Very cool stuff.
