I mentioned on Wednesday that there wasn't anything Lovecraftian about Fallout 4, but I may have been mistaken.
Take this with a grain...no, an entire bucket filled with salt. I was contacted by an anonymous source who claims to have knowledge of the project. According to them there is a non-trivial amount of Lovecraft-related material in the main game, and more is included as part of at least one DLC package.
If true, it's something I'm very happy to hear.
That said, I have considerable doubts about the validity of that information. For one thing, leaking it is what video game developers refer to as "a career ending move". Talking about it is a huge risk in light of the NDAs signed by everyone involved with the actual game. Beyond that, with all the media attention the trailer generated there's a huge demand for more information about the game. To be quite honest, this isn't the venue to release a tidbit like that. Not when you could contact someone at a major website and create a firestorm of attention by leaking it to them.
But man, it would be really cool if it's true.
