I like text-heavy games and agree with the GP that they are not nearly as common as they used to be. Voice acting is almost universal and most games require subtitles to be enabled to have much of any reading.
Sure, are some games like Disco Elysium, Pathfinder Kingmaker or other D&D-style games, which are big walls of text with minimal voice over, but let's be honest, those games are targeting middle-aged people, not 10 year olds.
The games kids are playing today involve very little reading.
If I go on itch.io right now and pick something at random, the likelihood of it being both made by a teenager and involving written storytelling is quite high. Likewise a huge hit of the last decade was Undertale and it had the kind of success where I recall seeing kids draw the characters in chalk on the sidewalk. The evidence indicates that writing never went away, it's just not upheld by large productions(and even then, Nintendo regularly eschews voice acting).
To me, there's nothing sacred about text, it's just a medium.
