I moderate a mainly German-speaking (English and other languages are also welcome) OpenTTD community on Feddit. Questions about OpenTTD can be asked there. I will also regularly inform about the current development status of OpenTTD. I hope to welcome more people to the community soon. Here is the instance agnostic link !openttd@feddit.de
More people should play OpenTTD. It’s free, open source, has an active community and runs on any smart toaster. Not to mention it’s a fun, chill game with a surprising amount of depth to it.
I played the demo that came with an issue of CGW or something like that in a floppy for a crazy amount of hours and it was a tiny part of the game.
