I kickstartered the Primeval Thule campaign setting. Mostly based on the names of the people involved; I don't anticipate doing much with it (or any campaign setting) other than reading it for the fun of it for the forseeable future. http://www.sasquatchgamestudio.com/
And I bought the DCC RPG and a couple of modules, again just for the fun of reading it.
Timing - can't remember, I think within the past six months.
One of the many new Pathfinder books (Mythic something), a copy (my third) of the 2nd Edition of MERP (we start a new campaign soon) and some weirdo old avalon hill time travel rpg I found on ebay.
