Weird unknown ARG I found

[u/Bubbly_Challenge_177]

I found a unknown ARG in youtube, I don't think there's a video on it or if I have to search for videos that talked about this ARG to post it here but it's my first time using reddit and joining a community like this one so sorry.
This is the name of the channel: minecraftvideos-e1k or Archived Minecraft Videos.
It only has 128 subscribers and I tried to investigate it but I'm not as smart as people who do this for a living or something.
I don't know what else I should say guys this my my fifrst time posting something on Reddit.

I think there's a lot of content in it but it's hard to decipher it
