So in a lot of the forums lately, especially regarding the announcement of the new DLCs, I've noticed people saying that Bethesda seems to have a hard-on for HP Lovecraft. I even saw some people saying something along the lines of "Instead of cramming the Fallout universe full of nonsensical HP Lovecraft references, why don't they just make a damn Cthulu game or something?" Well, as it turns out, they actually did! In an obscure Bethesda title known as Call of Cthulu: Dark Corners of the Earth. You can read about it here: http://store.steampowered.com/app/22340/ It's old, it's clunky, and apparently it's full of bugs so gamebreaking you need a fanmade patch in order to actually be able to finish the game. It's also from 2006, to put a date on it. So yes, it looks like FO4 isn't their first foray into Lovecraft.. well.. love.
