Interior and outside Lighting feel
I think it would be very important to think about how the lighting ingame feels right now. For example the torch lighting radius is too great and you can't appriciate it. The ingame lighting feels quite wrong and out of character because nights are not pitch black and if you have wall torches inside there is no appriciacion for them because the inside of the building is still fairly bright eventho its night time. A similar approach could be taken like it was done to Space Engineers where you can modify the light radius and intensity of the torch, however the outside and enviromental lighting is a core game fix. The fix that can be applied to the torch based on SE can be a temporary fix until a much more concrete fix is applied which will buy time.
