The bulk of what I buy continues to be books from the OSR for use with D&D, but there were a few exceptions. I grabbed Ryuutama's PDF when it was put up for sale, and then quickly upgraded to a hardcover. The game looks like an SNES manual, and doesn't remind me of any other RPG I've played. I backed The Warren on Kickstarter because I thought Bully Pulpit's previous game Night Witches was well done. That book arrived at the end of the year and looks to be the game about rabbits I didn't know I wanted to play. I finally bought Dungeon World, after enjoying Perilous Wilds so much.
There are lots of cool zines and small modules being put out by individuals in the OSR now. A Pernicious Pamphlet and In the Woods are stand out examples of this sort of work. I am hoping to make a zine from bits and pieces of my Carcosa game this coming year.
I only bought one book from Wizards of the Coast. The stuff they put out isn't really of interest to me. I wish they had an indie-imprint doing more interesting work. Out of the Abyss is an enjoyable read, but it's also large and cumbersome, and I can't imagine actually using the book to run a game.
Before this post I wrote False Readings. After this post I wrote OSCon 5.5.
