I heard today that Pelgrane Press is discontinuing their Dying Earth
RPG effective May 1st. Until then, the books they have left are 50% off at their store, and their PDFs are discounted at RPGNow and DriveThruRPG. I thought I'd mention it in case anyone has been putting off picking up any of this stuff.
I haven't played the actual game, but it looks pretty good. I have read through some of the supplements and they are excellent.
