Slightly off tangent, maybe... but boy do I miss Macromedia Director. It was a big part on the beginning of my career.

Director allowed quick development of Multimedia catalogs and even games. I wonder nowadays, what has taken its place? Let's say that I want to throw together some media assets, sincronize it's behavior, add some functional logic and package it all as a standalone binary to distribute, what should I use? An Engine like Unreal o other? Is there any authoring tools for that?

This are totally honest questions. I don't know the "state of the art" nowadays and if is even possible with an acceptable learning curve for someone to do that kind of things we use to do with Director
