Red Cross Hurricane Sandy relief RPG bundle on Drivethru.
$20 for $438.64 of downloads. Complete list and link in the RPGnet thread which also links to direct donations and other charities DriveThru supports.
Adventures, sourcebooks, novels, floorplans, map packs, and entire RPGs.
Contains three things I’ve actually heard of, and (ew) a game by Postmortem, but I’m sure we can find something useful or interesting in there. Among other things, four adventure-hook-y planets for Traveller and two horror adventures illustrated by Storn Cook.
Also available: a smaller bundle from Point Of Insanity Games.
