Just wanted to mention how essential this add on is for me. I laugh because I was hesitant to install it when it was first released, just becuase I didn't think I'd have much interest in factories. That was before industrial revolution was released. Now this is by far one of the most important add ons to SS, and one of the only ones I haven't started a new game without. I still havent even seen every single plot, but i managed to see a couple of the interior plots before starting over, so I really look forward to starting from scratch and seeing some of the new ones!
