made a multiplayer logistics game where 4 players have to connect their supply chains (runs in browser)

[u/goldenking55]

i wanted a supply chain game that a group of friends could actually finish in a single evening, so i built FourCities.

it’s a session-based transport sim. you manage one city, and 3 other people (or AI bots) get the rest of the map. to level up your city, you need to build rail networks and trade resources.

the catch is the geography. if your city needs steel, but the only iron mine is in your friend's territory, you have to either pay them to deliver it, or pay a massive "border tax" to build tracks straight into their land and mine it yourself.

it runs entirely in the browser using PixiJS. no downloads or signups.

you can play it here: fourcities.app
