A Forged in the Dark table-top role playing game about finding · By Orion D. Black
I've played a bit of Blades, but I'm unfamiliar with the practice of 'modding' TTRPG systems. Is the difference just in the setting flavor?
The framework of Blades is there, so you'll be comfortable with most of the mechanics if you've played it. But there are new/different mechanics, a new setting, and a different core focus.
