In my world in the 80's games roughly divided into two groups. On one side shooter-action-dexterity-2d-vertical-horizontal-scroll-non-scrollers™ and adventure games.
And I wasn't one of those, whose favorite after-school activity was trying to completely break a Competition Pro (... not that that was possible). My world was definitely adventure games and besides the later titles from LucasGames, especially games like King's Quest, Space Quest and later Leisure Suit Larry from Sierra On-Line Systems excited me.
Accordingly, my hands got sweaty when last fall Ken and Roberta Williams announced, they were working on a new title.
Out of retirement, into working life. That's how I like it!
In the meantime, there is a lot more information available for the release of Colossal Cave 3D Adventure, which is scheduled for fall 2022. And if you want to follow the work in more detail, you can do so via the ColossalCave3D Twitter account, which was opened especially for the game.
Let's hope, that zeitgeist and current technology won't get in the way of the project and that the spirit of Sierra Adventures will be revived.
By the way: For those interested, spectrum.ieee.org has portrayed Roberta here and it is a fine read.
