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.
