Does paying for a texture DLC mean we're headed in a new file structure direction? It's not hard to change ground textures and once they're in the public domain it's not that hard to distribute them to whoever wants them for free. I'm not advocating piracy but I can't see anyway of stopping it with the current file structure.
It is the same situation in FSX. The file structure is completely open, with no build in copy protection. Users can access everything, yet 3rd parties can still sell their stuff successfully despite piracy.
