If you're like me and wasn't within driving distance of a FLGS on Saturday you now have another chance to score some of the loot on PDF. If you have a facebook account search for and "Like" Free RPG Day. They have links to some of the booty that we missed out on.
I especially like the 1st Level Pathfinder module, very nice. Hopefully they'll link up to the Dark Sun Arena module. Cheers.
