Hi Product Hunt! 👋 I love deep logistics games like OpenTTD and Transport Fever, but getting a group of friends to commit to a 40-hour sandbox campaign over a weekend is basically impossible. I wanted a multiplayer transport tycoon experience that could actually be finished in a single evening, without forcing anyone to download a heavy client. So I spent the last few months building FourCities. It’s a real-time, 4-player transport simulation that runs entirely in the browser. You manage one city, and 3 other players (or AI bots) manage the rest. You build rail networks, manage rolling stock, and trade resources. If you lack local resources like iron or coal, you can negotiate trades—or pay a massive "border tax" to aggressively lay track into opponent territory and extract it yourself.
