• CPU/GPU:
  1. Start (04:00 AM, Seattle Port): Rain hammers the windshield. The Realistic Rain mod kicks in. You hear the wiper blades squeak. You connect the yacht trailer (requires precise backing due to long overhang).
  2. The Detour (I-5 South): A random event triggers—a jackknifed semi blocks the left lane. You must exit into downtown Tacoma, adding 20 minutes of city driving.
  3. The Weight (Oregon Mountains): The yacht is heavy. On the Siskiyou Pass, you downshift to 3rd gear. Your engine brake (Jake brake) echoes off the canyon walls.
  4. The Destination (Nevada Desert): Leaving the forest biomes of Oregon/Washington for the desert of Nevada is visually jarring. You park the yacht at the Sunset Casino (a hidden delivery point in the Heavy Cargo DLC).
  • DLC bundles change purchasing decisions; players often wait for sales to acquire large DLC libraries—this shapes the active playerbase in different regions.
