"WHEN YOU RUN AN RPG, DON'T CALL FOR A ROLL JUST TO ROLL! CHARACTERS CAN ACCOMPLISH ACTIONS WITHOUT ROLLING! ROLLS NEED STAKES! ADDRESS DANGERS, NOT TASKS, BRO! MOST 'PERCEPTION CHECKS' ARE ESPECIALLY BULLSHIT BECAUSE OF THIS! FOR EXAMPLE,"

Scene-framing GM tech: Start w/ color palette. When you describe the rest of the scene, the players will paint w/ those colors in the mind's eye. "The snow palace. The colors are white, pale blue, and silver." "The foundry. The colors here are inky darkness and fiery red light."

It's official! @EvilHatOfficial is publishing SCUM AND VILLAINY, the first standalone "Forged in the Dark" game. So exciting! This game is great.

Thing I learned after releasing Blades #34 : Even with Han Solo, Firefly, the friggin' Underground Railroad, and 18 suggestions in the book, a lot of gamers go entirely blank when they try to conceive of exciting smuggling adventures.

I know what I'm doing. I'm an expert in my field. But I have days where I don't hit the mark and things don't go how I want. It's not because I suck. It's totally normal. Don't hate on yourself. You're amazing. Carry on.
