I get commissions for purchases made through links in this post.
Sword Breaker Issue No. 4 - The Tempest Riders, PWYW. This is a great issue about air ships and air pirates.
Plundergrounds 3: The Hoard is available for USD $2.00.
A Gem most of you may not have heard of, John Harper's Wildlings RPG. A game about young tribe members coming of age.
The Wormwood Throne/The Wormwood Crown is another cool game draft by Ben Milton.
StormHack SRD Lite, a neat Pocketmod game. OSR fusion of Stormbringer and Whitehack. With Demons.
MAZES & MINOTAURS Core Books. Judd Goswick recommended it as "OSR with the Old Game reimagined as inspired by Greek Myth rather than Middle Earth."
I somehow missed Slade Stolar's The Indie Hack SRD. There are some interesting ideas here.
Perchance, a web app that can create all kinds of outputs.
