No Quarter Fantasy Rules
From Chris Gilders comes No Quarter Fantasy Rules. These free wargames rules are a massive work, with 83 pages in the main rules book alone. There also are a large number of army lists, which is the real strength of the set. Like many fantasy games, figures are defined by a model profile, detailing combat stats, actions, strength, toughness and wounds. This is an amazingly comprehensive work for a free rules set, covering every aspect of fantasy warfare you could want.
Dungeon Janitor’s Apprentice
Dungeon Janitor’s Apprentice is a two player storytelling game. The author writes:
Dungeon Janitor’s Apprentice is a storytelling game for two! One player is the Dungeon Janitor, who wants to get the dungeon cleaned as quickly as possible. The other player is the Dungeon Janitor’s new Apprentice, who wants to get stuck doing as little work as possible. These two characters argue by making up backstory for the dungeon.
To play, you’ll need just some tokens and the rules. You’ll get a double-sided PDF that you can print and fold into a little rules booklet (as well as a plaintext version). On the back of the rules is a labelled dungeon map to help inspire players during play.
