It says this on every route DLC for TSW: Powered by Simugraph. As if it was some kind of-sub-engine to UE4. Others say it's a tool. So, what exactly is it? Saying the information I could find about it on the web is "basic" would be like saying pressing the palm of your hand down hard on a hot plate will be "inconvenient"... Has anyone been more lucky with finding something?
