Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

OpenTTD v15.3

👉 An open-source transport simulation game based on Transport Tycoon Deluxe.

OpenTTD is a business simulation game in which players build and manage transportation networks, including railways, roads, air routes, and shipping lines. Inspired by the classic Transport Tycoon Deluxe, it expands on the original with improved graphics support, enhanced gameplay mechanics, multiplayer capabilities, and extensive modding options. Players can transport passengers and cargo efficiently while growing their transport empire in a dynamic, evolving world.

OpenTTD requires a base graphics set to run, which can be downloaded automatically on first launch or installed manually. Options include OpenGFX (graphics) or original Transport Tycoon Deluxe data files, which require owning the original game. Optional sound and music sets such as OpenSFX (sound) and OpenMSX (music) can also be installed via the in-game content download manager. Additional graphics, sound, and music content can be downloaded directly within the game. Transport Tycoon Deluxe can be purchased alongside OpenTTD on platforms like Steam and GOG.
