Glad you asked pelican. For starters, LFS isn't meant to be modable, not that much atleast. Second of all, it shows where LFS has a serious weakness and can be broken into and then possibly sold off in some black market and illegally made some cash with some things that aren't really in LFS. Third of all, I'm pretty sure I am right when I speak of the devs that they didn't want their game to be turned into some bus or whatever sim, mainly because that is not what they had put in the game, nor intentioned to be visible to the public which can be quickly be turned against them.
Lastly, every link and thread I find will be deleted because of those reasons, and more.
