Open TTD

An open source clone of the Microprose game "Transport Tycoon Deluxe". It's 1950, you've been loaned 100,000 and you've got 100 years to prove yourself a Transport Tycoon. Transport Tycoon Deluxe presents you with a choice of four vast game worlds made up of numerous small towns and raw material resources. If you'd prefer, you can even create your own game scenarios using the world editor.
