30 years ago they were also "archaic" in technological capability sense.
People played those games well into the era of Amiga and Atari level graphics, and played them for what they were, not because there weren't graphical games available in abundance.
As graphical games got easier to produce, that gap shrank, and text adventures did get less and less vital.
What I mean by archaic is people aren't used to playing text-only games now. They were then, so much that Zork was the best selling computer game. I mean, Minecraft is pretty archaic in terms of technical capability, but it's not archaic as a style of game. It's actually pretty popular, and a lot of people would call it beautiful and innovative.
Hadean is bringing back a long-dead (for over 20 years, again according to Wikipedia) style of game with a modern twist. Text adventures were popular three decades ago, then died out, and this game hopes to bring them back to a modern audience.
If they weren't popular 30 years ago, this article wouldn't be talking about them becoming more modern, so really you're just rewording the entire point of the article.
