I've been going down a rabbithole of people making Minecraft Found Footage ARGs using alpha/beta versions where "sooper sp00py" stuff happens, all the while split second codes show up on screen for other video or imgur links.
Quality ranges from just being OK to "what the fuck is happening, lmao?" Example being this one channel featuring a sentient AI player that accidentally got out from the 2011 california blackout, and the FBI got involved with shutting down any direct download links to the AI player, listing it as an "active endangerment to children".
Some of it is mildly interesting. Like this one channel that features an alternative development cycle of Minecraft alpha 1.0.16 that seems a little more "fantasy" oriented compared to it being a bit more grounded in its lore.
You can also play these modded versions apparently
Most of it is a bit dumb and out there for what it is (FBI, secret shadow admin groups, what have you), but I think compared to gay shit like Mario 64 beta ARGs found footage type channels, these videos feel at least a little more believable since with "creepy" Mario 64 videos they feel so incredibly fake on the basis that you expect me to believe a game made by a Japanese toy company would just have VHS footage lying around of anomalous affects going on in a 30 year old game (in English no less)?
But with these Minecraft videos, there is the possibility that yeah, some kid from the 2010s big into Minecraft, may have actually recorded something anomalous on camera and posted about it or kept it hidden for a long time hoping to forget about it. On top of that, some of them do go above and beyond with trying to sell that these were recorded back in 2010-2013 as you can see a person's desktop running Windows 7/vista and having shit like Skype and old program logos installed instead of using their modern iterations.
I don't know, it's nothing amazing or groundbreaking, but compared to the tranalog horror slop that permeates the horror sphere, these feel at least mildly intriguing to watch.
