The Magnus Archives. It's been described as 'like British Night Vale' but that doesn't cut it. It's genuinely creepy little twenty-minute anecdotes that I think might link together into a bigger plot. Definitely goes heavier on the creepy than Night Vale does, and is possibly better for it. Definitely its own beast, and thus far, recommended to anyone who wants some creepy horror with a plot - or, more straightforwardly, anyone who has already spent more time than they should on the SCP Project.
