All the inside sources indicate that EAxis has seriously cracked down on the actual moddability of the game. While surface-level texture replacement and remeshing will easily be possible, making actual SERIOUS modifications is looking considerably more crippled. The kind of easy stuff that we have gotten used to in TS2 simply will not be possible in TS3. It are a fact. I know because of my learnings.
Does that mean we'll have to live with all EA's bugs they never bother to fix?
