Dear Walfaenger!
I am happy that you like the complexity of space combat. I was always planning for environmental factors affecting ship's functions, like the aforementioned stellar interference as well as from the system surrounding nebula and from asteroid rings. Currently there is only one such effect at play the sensor shadow that limits detection to power signature level if there is a planet between two ships that are in sensor range to one another.
A distance based stellar interference with increased severity on various functions of a vessel as getting closer to the sun is a good idea, although it might complicate things so it probably be an optional feature. First i plan to implement a buff and debuff system for space combat, since right now adverse effects like EMP is not displayed on the ui in any meaningful way, this would be a must for any environmental effect going forward. I am thinking things that affect power generation, shield resistance, targeting interference, sensor efficiency etc. Some of these could also be put into modules and used as abilities, a thing that i would very much like to put into the game in the future.
Kind Regards!
