I think you misunderstood Sancho. It's not a "true harem". That's why I mentioned the overlapping scenes and the "head cannon". I can just play every path and see every scene I care to see and make up a way for them to make sense or happen simultaneously in my head in a way i can still enjoy the story.
Simply put URM notifies you whenever there is a split path or a new scene can be triggered. I simply change variables in order to trigger every single one, rollback and then move forward with the one I liked better. Knowing that further along I can just adjust the variables again to see what I want to see. And like I said so far I've been able to trigger literally everything I want with a single save even though none of the paths are compatible. I have not yet noticed any roadblock set up by DPC that prevents me from seeing anything or follow a given route.
I can't enlighten you. All I have is basic knowledge of Python and all the coding I do is in SQL with basic queries to fetch the data I need for my job. All the messing around I do in these AVN's are through editing tools like URM. But hey, it's been working great so far
