This one isn't analog horror exactly, more like digital horror tbf... But Valle Verde is a really cool project. It's an made by Alluvium.

If that doesn't float your boat, I think Angel Hare is pretty cool and it's more analog horror oriented.

Both of these, I love a lot tbh.

One I watched recently was Pretty Girl, an FNF arg, I think it's mid but noice BUT OH GOD DON'T WATCH THAT ONE BATMAN ANALOG HORROR. PLEASE.

Super Mario 64 Beta Archive, a sadly unfinished ARG

and BDG's "Teaching Jake about the camcorder"

those are the only examples I know that I'd consider good. also maybe LOCAL58 but I haven't seen much of it

when are we gonna upgrade to digital horror
