Artist! Quote with your badass woman 🏮
A digital sketch of a woman wearing armour made from human arms and skulls linked together by grasping hands. A portion of her face is cracked and rift with fissures across her face, revealing a fleshy texture beneath her skin. One of her eyes is glazed over and white. 
She has four arms, two of them are holding weapons, while another holds aloft a glowing lantern made from an altered human skull with one very large ocular opening to serve as the primary source of light from the lantern.
Her fourth arm is holding the corpse of a large creature over her shoulder. The creature has large teeth, spines along its back, and fins down its sides.
Perched on top of the dead creature is an otter-like companion. Both the woman and the otter are looking off into the distance, the lantern presumably illuminating what they're looking at.

Artist! Quote with your gloomy art!
A digital sketch of a large stone monolith. Embedded in it s a skeletal humanoid, its skull is missing its upper half and the sternum is extended down into a point. its forearms and hands are also protruding from the stone. 
The stone is also engraved with markings and writing.
At the foot of the stone, a figure is knelt in front of it, one hand placed on the face of the stone.

I'm cautiously optimistic about RPG Trader. If you don't know, it's a new platform for buying and selling rpgs just like DriveThruRPG, Itch, and Lulu. What's making me optimistic? It's rpg-focused. It does away with the 5-star rating system. It has coherent product categories. rpg-trader.com

When a dragon has just 1 hit point and a maze of obstacles, combat is like an open-ended puzzle. The challenge: the player characters only have 1 hit point too—and the dragon has a lot fewer obstacles. A small playtesting update about death without hit points:

Dying from the 1 HP Dragon
How does life and death work in this game without hit points?

I will always find a game designed for a hyper specific thing to be way more interesting than something generic. “In this game you play as space pirates who rob space trains” is way more compelling design than “This is a space game where you can do anything.”

DriveThruRPG/Dungeon Master's Guild is bad for the industry. They take 30-50%. Discoverability is terrible. You're competing with slop, which turns customers off from third-party in general. You have no way of knowing who bought your products. You can't offer better discounts on other sites. 1/5

Lots of tech dudes think the "idea" is the important part of creating, not the creative journey you take through work to give that idea actual meaning. Ideas are the easiest, cheapest and least fulfilling part of it. Giving ideas life through work, and sharing that work with others, is the stuff.

I'm designing outside of D&D 5e or 5.5e at this point, HOWEVER, I am fiercely editing a really fresh and weird genre mashup for it: Serenity Springs, a 1950's horror setting & adventure. The kickstarter is up, check it out if it strikes your fancy 😊 www.kickstarter.com/projects/gri...
Says "Freaks from Beyond the Hayze: A Serenity Springs Adventure." across the top. The art shows a black and white suburban street with several DnD characters in the mid-ground. The foreground is full of people in 1950's-appropriate clothing looking scared and confused. The characters contrast the foreground people and the rest of the image, as they are red.Says "Serenity Springs: Realm of Noxious Nostalgia" across the top. Depicts a couple sitting down to dinner inside a 1950's-style diner, while a giant flying bug monster menaces them from just outside their window. The Grinning Portal Games logo is in the bottom left and the 5e compatible logo is in the bottom right.
