That’s a neat idea. Keep the wind and water as tangible checks—players can roll to see if a desert wind shifts or a spring dries up—so there’s a clear consequence. For social ties, maybe a quick dialogue choice that either opens a caravan gate or gives a rumor that can save a night’s travel. Balance the dice so you’re not stuck in a stalemate, but let the choices feel like real decision‑making on the move. A bit of unpredictability keeps it exciting, while the underlying logic stays true to how real nomads navigate.
