Ok so I have two possible new set ups for this game since I feel like this cave generation and exploration will go better if we change a few things up.
Heres the two major ideas I have for it. Both of these ideas keep the general idea for this game intact while changing some of the set up and environs. Mostly to allow a more focused experience with less faffing about not knowing where to go.
1. Deep Carbon: Scientific drilling has uncovered, miles deep within the earth, a honeycomb of caves, rivers subterranean seas and unseen life forms. The nature and scope of this discovery has been kept secret and governmental powers are eagerly exploring the substrata, looking for anything they can use. Originally scientists and "real" explorers were used but the lower worlds proved too dangerous, so now all manner of prisoner, mercenary, loner and men who will not be missed are used. The players are stationed on a
drilling ship and inserted deep into the earth to explore. Sometimes they will have specific objectives, sometimes they will just be tasked with figuring out what this place is.
2. The Bowels of God: Earth has been eaten. Or perhaps it is still being eaten. No one knows. But you're inside it; trying to make a living in a world of flesh. Explore the labyrinthine guts, meet other races that have had their planets destroyed, interact with the parasites and generated species within the belly of god, and try to make sense of this new and hostile world. Has anyone seen episode 4 of the samurai jack season 5? Yeah, kind of like that.
So one of those settings is what I'm thinking of.
As per a system, I'm working on that now, it will be done soon. It is short, easy and designed to be far more usable and generalized so we don't have hyper focused people who suck at everything but one task.
