From Unformed Realms – New Review
Since From Unformed Realms is essentially system-less, it serves as a great resource for creating new strange monsters for many games. I have personally used it for The Black Hack itself, and for Portal Rats, but not for The Cthulhu Hack itself (yet). Next up I plan to use it for Macchiato Monsters.
