What is OpenTTD?

This business simulation and sandbox is an open-source remake and expansion of Transport Tycoon Deluxe. On procedurally generated maps, you connect towns and industries by road, rail, water, and air, moving passengers and cargo through production chains while expanding capacity as technology and demand change.

For you if...

+you enjoy optimizing complex transport and production networks
+you want sandbox management with solo and multiplayer options
+you like expanding systems across procedurally generated maps

Not for you if...

−you want a story-led game rather than open-ended management
−you dislike planning routes, capacity, and cargo transfers

What players say

95% of 17,007 reviews are positive

Players praise the long-running transport-management loop, especially designing rail networks and signals. The dominant recent complaint concerns a storefront access change that bundles the open-source game with a paid original; players note that OpenTTD remains free from its official website.
