Don't follow much YT channels but big fan of Switch Up, they do new releases videos, sales videos and reviews.
Previously, when I used to listen to podcasts, I followed:
- The Kit & Krysta Podcast, they used to work at Nintendo of America, then left and started the channel. Didn't follow their channel, just listened to their podcasts, that used to have news and some other behind the scenes stories of Nintendo or gaming etc.
- Punching Up, the Nintendo podcast of Last Stand Media, mainly followed it cause I used to listen to their PS podcast (Sacred Symbols). This has different cast, and I didn't follow it for long, but it has been around for over 100 episodes, so shouldn't be too bad.
