A Magical Society: Beast Builder. Atlhough for d20 system, this isn't some “roll X dice randomly, get a monster.” Like other books in the series, it offers a detailed take on how to create beliavable, exciting, and dangerous monsters that fit into your fantasy world.
Wizards of the Coast has announced they'll update the Open Gaming Licence. By update, they of course mean they'll reduce what one is able to do, introduce new ridiculous restrictions, and sabotage their existing fan base who are promoting them for free.
Ever since 4E there's been a lot of discussions regarding how irrevocable OGL really is. In the wake of recent developments, Alexander Macris (creator of the excellent Adventurer Conqueror King System) offers an interesting take:
Lost City of Gaxmoor (digital and isometric maps). A city that was gone for a thousand years reappears. Of course it's full of shit that wants to kill nosy adventurers. Plane of chaos breach the reality from time to time.
I've just seen that Frog God Games is running another sale with discounts up to 70%. As before, most of my suggestion below are for the Swords & Wizardry system, a retroclone of Original D&D.
In no specific order, I can recommend the following:
Monstrosities (Swords and Wizardry). Nearly 500 monsters. Each monster comes with an example encounter/nano-adventure. Includes tables with monsters by challenge level, guidance on creating new monsters, tables of monsters by terrain, and tables of random encounters (3d6, so bell curve).
The Northlands Saga Complete (Swords and Wizardry). A compilation of ten adventures set in stereotypical cold north. Probably enough for several years of gaming. My favourite activity is stealing from this book and including parts of it in my own game. Tenfootpole has reviewed first four adventures back in the day (NS1, NS2, NS3, NS4). $18 is a steal for this.
The Lost City of Barakus (Swords and Wizardry) (local and regional maps). Perhaps my favourite Necromancer Games mega-dungeon—because it is so much more! You get a starting city (with seven adventures), a wilderness area (with 26 keyed encounters and mini adventures), and a mega-dungeon with interesting factions and cool big-bad. Suitable for low-level parties.
Bard's Gate (Swords and Wizardry) (player's guide). A massive city packed with urban encounters and adventures (8 included, from levels 1 to 10+). Very dense book. Some say this is FGG's finest product. The truth is that this is another Necromancer Games revival. And that's why it's great. :)
The Book of Taverns (volumes one, two, and three). Had enough of generic taverns and inns, but short on prep time? Steal one from here. Again, these are revivals of old Necromancer Games books. They are good.
Robert Conley just shared some delightful news about Majestic Fantasy Realms, the spiritual successor to the Wilderlands of High Fantasy:
By next year I will be releasing stuff for the Majestic Fantasy Realms which is formatted similarly to how Blackmarsh is set up. Except it will be four 12” by 18” maps. There will be some city/town maps included but nothing like the original CSIO. For that I have a long term plan for what I call the City State of Eastgate. Basically picking up from where I left off in 2009...
Here is how the maps look at the moment:
It should come to Kickstarter next year, so keep your eyes open.
In the meantime, the following are available from Rob's DriveThruRPG:
