The print issues of Fight On! have been reduced in price until the end of the month. Also, a spiffy prestige all-in-one hardbound of the first four issues is available until April 1 if you'd rather get all that gaming goodness in one book. If you don't have FO! in print now's the perfect time to get it.
UPDATE: Also consider checking out Calithena's Campaign Compendium, 54 pages of notes from the editor's long-running fantasy world.
