I want to ask one question:
Maybe you’re the developers, but I want to ask how the mods will go on Steam version (maybe Workshop?).
And yeah, I know that many mods will be included into game, but it will be probably also new things to install.
Greetings
Getting the Steam Workshop to function with the game is one of the first things we look into as soon as we are on Steam! 
It will probably work even with the mods on the forum. It works with BeamNG.Drive!
Yes, without the user friendliness of the Workshop it does work, you can still just extract things into the right folders and add cars & stuff. We really want proper mod support though.
