I added the floating dynamic light for a number of reasons TBH.

Part of this RPG Sci-Fi concept is that the suits worn by players provide essentially everything the player needs to exist in hostile alien environments. Each character has 50-60 stats including energy, so I really liked the idea of putting players in incredibly dark levels and need to manage their energy to keep the light on...

On a more practical note I am also thinking about how to use dynamic lights to increase the visual quality with special effects, melee attacks, telepathy and so on. I've already implemented simple dynamic lights for the telepathic attack you can see in this short video, so far I am happy with the basic results.

My priority is to get a working demo for proof of concept up and running so that I can demonstrate confidence in this technology for delivering the product, so any feedback is much appreciated
