I've been on a Castles & Crusades kick lately. It's nice being able to break out all the old modules I grew up with without having to jump through a bunch of hoops to make them play "right." Reading through stuff like Castle Amber, Needle, and Secret on Bone Hill has had my mind racing and giving me a huge push towards running games again. It's been great!

Between that and Sandbox Generator I've been able to put together a mountain of content for my players to poke at as they see fit.
