A 4X Trade Sim             
 
Waypoint I

Overview

This game is set in a world responding to and already transformed by the climate crisis. It freely explores what a world profoundly altered by climate change might look like while remaining grounded in real world solutions such as those being implemented in the global merchant fleet today.


Waypoint II

Gameplay

Sail Cargo puts players in command of a growing cargo fleet on a globe of the Earth and tasks them with rebuilding international trade routes. A strategic sailing sim, directed top-down, featuring events on the water and in harbor, and a robust simulated economy. Players decide on trade routes, investments, expansion, and how to deal with everything from pirates to food shortages, to government bodies and unpredictable weather.

01

Fleet Command

Start with one ship, grow a fleet, Left Click to select a ship. Right Click to chart a course, drop anchor to discover foreign ports filled with trade opportunities, stories, and choices.

02

Ports

Differing locales feature different opportunities: resource production, resource refinement, buying and selling goods, storing goods, hiring crew, building and retrofitting ships, and special delivery contracts. Ports evolve with player investment over time.

03

Crew

Ships require rations, crew, resources, wages, and morale. Neglect a crew and risk desertion, mutiny, or death.

04

Trade Routes

Set stops and orders in an automation layer and let your ships run themselves. Only high-level problems get flagged as notifications needing player attention.

05

Exploration

Our world, changed, reveals itself as the player explores the globe. Newly discovered ports offer new opportunities.

06

Win & Loss

Ships can sink, be stolen, or otherwise lost for good, crews can desert. Skilled players will be able to optimize shipping routes, curious players can focus on exploration.

Waypoint III

Ships

Ship design straddles a line between a realistic future of what freighter craft might look like someday and a somewhat romanticized Age of Sail nautical vibe: windjammers and barkentines, but also small freight craft.

The full design document, produced as a jam requirement, goes into more detail on the initial pitch, including a plot draft, climate themes, and more about world & UX design. It remains available to download below. This game was produced for Indiecade's Climate Jam 2026, where the theme was "Plant a Seed". Claude was used as a coding assistant.
