Subarctic route planning
The new subarctic climate includes fjords, marshes, pine forests, tundra and mountains.
Plan the operation
Treat fjords and marshlands differently: a water route through a fjord may be attractive while marsh terrain can be unsuitable for shipping.
Check the result
Inspect navigability and terminal access before choosing a mode. Do not assign climate-wide speed or cost penalties without game evidence.
