I also prefer blog posts to YouTube videos for most things I can skim read 10x faster than someone can speak.
I can't understand why people tolerate spoken instruction (the visual side of video content is a different thing entirely. That I understand)
Not only do people tolerate it, some people prefer it! I'm going out on a limb here as I have no data to back this up but I'm willing to bet that the average person has not done any dense reading since they finished their schooling. With that context, it's probably not hard to imagine why most people prefer video instruction over blog post and what not.
I know not everyone is ESL, but it shouldn’t be surprising that different people have different levels of speed and comfort with reading vs audio content.
It's not like this for everyone! Some people really enjoy looking at the art or listening to the voice acting or whatever. But please give me a skip button; I'm not watching a program, I'm trying to play a game.
Same with narration. Narration requires a fixed script; don't dare try to give your character a unique name. Text can be generated and modified on the fly to reflect a dynamic game environment. Adding a new sidequest doesn't require actors and studio time; just a gamedev.
