I first heard about this from Wargame News and Terrain.
Drivethru RPG is having a free bundle give away here. (link also from Wargame News and Terrain)
I downloaded it, plus bought some more rule books and the 3D card dungeon that Ricardo of Fantalonia mentioned here.
I also received a large box from a member of the Old School Wargaming Yahoo Group, so thanks to Robert I now have a bunch of cool stuff to sort through. I'll try to get some pictures up in the intervening days and perhaps you all can help me identify some of it. A real mix of scales and periods.
I also intend to do some gaming, by hook or by crook today. I just have a lot to do with a kids party, registering for fall football and the realization that the yard is way too dirty for an Easter Egg hunt. Off to the salt mines.
