Gaming

Doing a quick skim on my phone, your microphone quality is fine. I would probably lower the game audio in post a bit to make the sound more distinct, but it's only noticeable when the game does loud stuff.

I watched it on my phone in 1080p60 and the scale didn't bother me. It's not like I have to read a lot of text and the precise position of the player character is mostly irrelevant, too. Like, if you get hit by a train or something, the screen will flash red and you'll react to it, too, so I'll know what's going on.

Well, and I don't look at the screen at all times anyways. 🙃

Would like to see more of this journey...

Hey, not to discourage you at all, but from what I can tell most viewers are a bit bored by watching episodic Factorio videos. I would recommend creating longer-form videos that encompass your entire challenge rather than an entire series of it. It's a lot less video output for the effort you put in, but you have the advantage of being able to narrate the entire challenge as a story. If you want some good examples of this, check out Dosh Doshington's content. He doesn't post too often, but when he does it always does well.
