🌡️ Climate barriers are the red routes. A tropical crop crossing into a cool or arid zone takes one extra move. Watch items fade as they travel farther from their origin.
⛵ The Manila Galleon is the blue route. From 1565 to 1815 Spanish ships ran Acapulco ↔ Manila, where Chinese merchants met them — Mexican silver west, silk and porcelain east. Three to six months at sea, so it costs a move too.
