H.P. Lovecraft One of my biggest influences.
I wrote a little thingy about my fave horror author, good ol' HP, and shared some observations in general as well as what I think his best works are for people who have never read him before. Also shared a link to the awesome hplovecraft.com, where all his stuff is free to read online.
Check out the full article here if you like, and post your favorite Lovecraft stories, creatures, etc in the comments. I love this stuff, enough that I made a Doom mod called Strange Aeons, based on his novel The Dream Quest of Unknown Kadath (as well as Call of Cthulhu).
