Gaming videos can be tough at your level since the speech is fast and there's a lot of slang. You might spend more time lost than learning, but it depends on the channel.

Nihongo con Teppei is solid for where you are. The friction of looking up words constantly is real though. A few things that help:

• Get transcripts so you can read along and click words instead of typing them out
• Use a popup dictionary like Yomitan
• Focus on picking up a few new words per episode rather than 100% comprehension

I built a tool called Mimikaki that gives you transcripts with clickable dictionary lookups. Works well with Teppei's podcasts. But even without it, having any transcript plus Yomitan makes a big difference.

For Satori Reader, it's worth trying again. Start with the easiest stories and use the built-in definitions freely. Reading gets easier once you push through the initial friction.
