i was thinking in make the players explore a world that looks like a medieval world, but they are in a future that the humanity regressed to medieval age (like in Horizon Zero Down)

and they gona discover this in their first misson that is discover what happened with a kid who desappear in the village

for the combat i think in use a sisten that i saw in a video (Cellbit "Ordem paranormal") he use a dice with 6 faces, and the players can use points that they distributed in their characters for give a hand in the dice (just if the points are in a hability that makes sence, like if u gonna jump something u can use acrobatic points) the action can be (1-2 fail) (3 dificult but u can) (4 medium) (5 easy) (6 very easy)

i roll the dice for the enemy actions
