Temperature (hot/cold)
Environmental temperature acts on the character: cold zones drain warmth toward hypothermia, heat brings exhaustion, and survival requires clothing, shelter, fire, and route planning. Temperature layers geography with meaning — the mountain is not just terrain but a hostile system — and creates preparation gameplay: the expedition is won at the campfire where you packed for it. The Long Dark builds its entire loop on cold as the true antagonist. Designers use temperature to differentiate biomes mechanically, to gate regions softly (you can enter underdressed, briefly), and to make fire and shelter emotionally meaningful. Key decisions: layered clothing with warmth/weight tradeoffs, wetness interaction (soaked clothing in cold is the classic death spiral), daily and seasonal cycles compounding the system, and feedback clarity — players need to feel the cold coming well before it kills. Pitfall: binary comfort zones (fine/dying) waste the system; the interesting play lives in the gradient. Weather-event variants — heat waves and cold snaps — spike temperature for a stretch of in-game days, turning a background stat into a survival crisis players must see coming and prepare for.
