However I used to view day/night cycle as a full hard impossibility due to the lighting system being similar to Dos2. I've made a day/night/weather system in Dos2, and I'm happy with the results for how I implement them, but it's limited to outdoor areas and certain circumstances due to limitations. However after lighting changes in patch 6, I'm more hopeful from a technical PoV, but still not convinced due to expense > pay (not economic, but manpower and time investment). Lots would really want it for atmosphere and a sense of immersion, time passing etc, so the convincing to be done there IMO is more at why it matters for the experience and adventure at this point.
