Question 1

Is OpenTTD free?

Accepted Answer

Yes, entirely. OpenTTD is open-source under GPL-2.0 with no purchases, subscriptions or advertising. The free base graphics set means you no longer need the original Transport Tycoon Deluxe files.

Question 2

Do I need to own Transport Tycoon Deluxe to play OpenTTD?

Accepted Answer

No. OpenTTD ships with its own free graphics, sound and music sets, so it is a complete standalone game. You can use the original files if you own them, but it is not required.

Question 3

Is OpenTTD still being updated?

Accepted Answer

Yes. OpenTTD has been in continuous development since 2004 and continues to receive regular releases, making it one of the longest continuously maintained games in existence.

Question 4

What is BaNaNaS in OpenTTD?

Accepted Answer

BaNaNaS is the official in-game content service. It lets you download vehicle sets, industry chains, AI opponents, scenarios, heightmaps and graphics replacements directly inside the game, from a very large community library.

Question 5

Does OpenTTD have multiplayer?

Accepted Answer

Yes, supporting dozens of simultaneous players on public or private servers, either cooperating on one company or competing as rivals. Live server and player counts are shown on the OpenTTD servers page.

Question 6

How is OpenTTD different from Cities: Skylines?

Accepted Answer

OpenTTD is about transport networks between existing towns; Cities: Skylines is about designing and zoning a city itself. If you enjoy the traffic and logistics part of Skylines most, OpenTTD goes far deeper on exactly that.
