Toy N Game

OpenTTD is an open source clone of the Microprose game "Transport Tycoon Deluxe", a popular game originally written by Chris Sawyer. It attempts to mimic the original game as closely as possible while extending it with new features.

Over 30 language translations are considered complete, and OpenTTD is available for *BSD, Linux, Solaris and Windows.

Don't miss it, it is one of the best open source game that we ever get.
