OpenTTD is an open source reimplementation of the Microprose game Transport Tycoon Deluxe (TTD). As president of a start-up transportation company in 1950, you have a choice of building rail, road, air and maritime transportation routes to build up your transportation empire. Outsmart your competition by beating them to attractive passenger and commodities routes to become the game's highest-ranking transport company by the year 2050.OpenTTD is based on Chris Sawyer's Transport Tycoon Deluxe and introduces a whole set of new features, including multiplayer support, better stations and vehicles, larger maps and a host of other options. OpenTTD runs on Linux, Unix, BeOS, OS/2, Windows and a few other platforms.While the game is modelled after the original, OpenTTD has many additional features that enhance gameplay dramatically. OpenTTD has customizable game graphics, and work is underway to replace TTD's graphics completely. Many features were inspired by TTDPatch, a popular enhancement for TTD, while other features are original. OpenTTD is far more customisable than Transport Tycoon Deluxe through the use of Advanced Settings and custom graphics.Significant enhancements include the introduction of Multiplayer, railways tracks built with the Autorail tool and on slopes, Waypoints, trains that are longer with more engines and larger and more realistic maps. More advanced players can take advantage of presignals for more control over stations and junctions, an increase in the number of allowed vehicles, and more flexibility when it comes to stations.To make the game more enjoyable, new train pathfinders have been added to let trains find their way better, a convert rail tool to make upgrading easier and a bigger dynamite tool to make blowing things up a lot faster.
