I understand, I presume this is why AC's mod section on the official forums is now closed. Perhaps the better way to go would be to NOT disallow mods, but make it so VOB mods shouldn't be able to be posted here, unless it's a fictional car made special as a LFS mod. There are plenty of sites which host a variety of mods for a variety of games though, which begs the question why they haven't gotten in trouble because of that yet.
Finally, if VOB mods are normalised, then a basic framework should be made in order to support modding, atleast in a primitive way. Getting mods for LFS means going to a lot of shady websites, and the quality of the mods is sometimes lacking. That's not to say it's the modders fault, but ultimately LFS makes it very difficult to implement mods into. I hope Scawen will understand the potential of modding, and will become more open towards modding.
That being said, I would love to see some sort of track modding; altough it wouldn't be of the same quality as an "OEM" track from LFS, it would surely be beneficial for everyone. There are plenty of track mods that are very high quality, and if LFS permits the conversion from one game to another, then I believe that the original creators would be glad to make it happen.
Right now making custom tracks is a pain in the butt, and very poor in regards to the quality of the tracks themselves. While I understand that custom tracks were never the goal, thus the minimal "building blocks"; I believe that making it more easy to add tracks to the game would definetly quench the thirst for content of many players, and will stop the annoying "when's the new update coming?" threads.
