The only recent ARG I actually enjoyed and participated in was the "I Am Sophie" one, to be honest was one of the most fun ones in a while.A lot of tryhard ARG creators these days who think they can replicate major ones like that. Usually involve stealing spooky scary movie footage and using VHS video effects from free video editors.
Yeah people love using the clip from that, fuckin uh, 50s-esque horror movie where the dude laughs and shit, then stabs himself and then receives fellatio from "mother nature", shit was pretty bland, but weird ass plot.
Think it was called "Begotten"? or some shit, watched it on youtube a while ago.
