I bet there has been discussions about this in here and of course this is an important aspect of the game dev. but I couldn't find much speciffically about modding as much as possible to maximise the immersion and realism, I'm considering to work on a mod with features such as 1) Removing space dust (duh! It can become very disturbing if you think about it and of course space dust must go for this configuration...) 2) Minimising exteriour sounds in space or somehow finding a way to render those sounds in a way that makes it sound like it's coming from a high tech sensor that can capture sound in space and these two are the ones I can think of top of my head, I would like to update this thread as a note paper as I find more stuff like that, hopefully these kind of changes would be okay in terms of CIG modding policy since such a mod would not give any gameplay advantage in any way and can actually disadvantage users who are willing to use it.
