About OpenTTD

✦ AI summary

Build and manage sprawling transport networks across procedurally-generated maps, connecting industries and cities by road, rail, water, and air to earn money through increasingly complex cargo chains. This free, open-source remake of Transport Tycoon Deluxe lets you play solo or cooperatively while adapting to technological progress, growing competition, and an ever-evolving world shaped by thousands of community mods.

OpenTTD is a business simulation game in which players earn money by transporting passengers and cargo via road, rail, water, and air. It is an open-source remake and expansion of the 1995 Chris Sawyer video game Transport Tycoon Deluxe.

Build



Connect industries and cities on procedurally-generated maps of up to 4096 x 4096 tiles by building a network of roads, railways, docks, and airports. Navigate dense city streets, cross oceans and rivers, and conquer high mountains in one of four climates.

Transport



Work alone or with friends to complete production chains and transport finished goods to towns. Assemble a fleet of hundreds of vehicles, transferring cargo as needed in an interconnected, multimodal network with optional cargo destinations.

Upgrade



Keep up with technological improvements through the years as towns grow; new modes of transport are invented; and industries appear, change production, or fail. Expand stations and build network capacity to keep up with demand and avoid delays.

Extend



Customize your OpenTTD experience via community-made mods downloaded through an in-game content service, including real-world vehicles, new industry sets, custom scenarios, and more.

Free and open-source



OpenTTD is free and open-source software, licensed under the GNU General Public License version 2.0. OpenTTD is under ongoing development. OpenTTD is not an abbreviation of anything.

Game so good, can basicly run on a microwave. The only sad part tho is that you need like 2h or more of tutorial to really understand the game well and have fun. Anyways, strongly recommend :)
