Curseborne is a spiritual successor to those older Storytell* game lines, World / Chronicles of Darkness. a new Urban Horror game designed with supernatural type crossover baked in from the start. made by some of the old hats from old WW and associated ppl who have been involved in the licensed products over the years.

It uses the Storypath Ultra system.

it’s made in-house by Onyx Path Publishing so they don’t have to deal with Paradox/White Wolf licensing.

addendum: Requiem was actually quite successful as a gameline, even if it could not outright replace Masquerade in public mindshare. but it doesn’t have to since they are different games, even if there’s overlap.
