I now find it impossible to make a scene without at least using relays. In fact, the simple ability of the binary choice of accept/do not accept trigger makes amazing things possible for scene control. Want to make a music player? Covered. Want a multi-layered contextual UI? Yup, sorted. The randomization options, even just using a SequenceChoice and EventSceneLoad mean that every time a scene opens it can be controlled and can also be a surprise - even when you've programmed the scene yourself. EventAudioQueueEmpty is just brilliant for timing. I'm working my way up to StateMachine, but I fear my mind may explode.
