Listening to the latest Ship of the Dead podcast, it was wryly amusing to hear Luke get told, to his face, that Ravaged By Storms was created because the Pirate Borg campaign book wasn't out yet, and they needed to create a substitute version for themselves.
Luke said, as the person creating 100% or close to it of official Pirate Borg stuff, there's only so many hours in the day, which totally makes sense. It doesn't make me want the Dark Caribbean sourcebook any less, but I get that it's not something he can just bang out.
And given that he created Pirate Borg specifically to support the Dark Caribbean sourcebook, it's clear it's important to him to do this right.
