Transport Fever 2 from Urban Games and Good Shepherd Entertainment appears to be turning into the ultimate modern transport sim and that's awesome.
With the latest update available today, they've expanded modding support quite a lot. The team said this update is a "big investment for the future" and we can be "assured that Transport Fever 2 will continue to be improved in the future".
For modding the scripting interface was reworked, there's a new UI, an in-game console for LUA scripting was added, custom cargo models are possible, they added support for dynamic game resources, per-save mod settings are possible and the list of what they've added to boost modding goes on for a while. It's also good to see Linux was not an afterthought here, as it's possible to do it on Linux too as the model editor has a Linux build and the new official Modding Wiki mentions Linux plenty too.
The focus wasn't solely on modding though. Simulation performance was improved, game speed throttling was updated to prevent "excessive stuttering", error handling was improved, keyboard shortcuts were updated to make Shift / Ctrl / Alt possible, the French / Spanish and Polish translations quality was improved and there's also a long list of bug fixes.
