OpenTTD
A clone of Transport Tycoon Deluxe
OpenTTD is a reimplementation of the Microprose game "Transport Tycoon Deluxe" with lots of new features and enhancements.
OpenTTD is playable with the free graphics files from the openttd-opengfx package and optional sound files from the openttd-opensfx package (which is in non-free). Alternatively, OpenTTD can use the graphics files from the original Transport Tycoon Deluxe game (See README.Debian on how to set this up).
