I sometimes wonder if it would be better if commercial ships had the same requirements as military ships in terms of maintenance and deployment but lessened to 10%. So such things still weren't a major concern but something you had to still keep track of.
A 'hardcore' mode where you can turn on deployment and maintenance for commercial ships and set how sever it is compared to military ships would be cool.
For RP purpose I add 1 size Active Sensor, EM, and TH to all ships. I am now playing a game with 1.5 EM and TH to "activate" military design to all ships and try it. I know few players play Aurora like that and I do agree the community now to be "mature" enough for an Hardcore Mode.
I'd do that as well except that I think 'military' requirements should be far, far less on commercial designs. Something like 10% as I mentioned previously; enough that you have to account for it but only just. Otherwise I fear it might make the game too cumbersome to play. What do you do for stations that are meant to stay out permanently? Sure a Recreation Module can handle deployment time, but what about maintenance supplies? You'd have to send a ship out periodically to top them up.
I am currently facing 2 issues which I have sorted in a different way. Stations are still allowed commercial as I think it's fair to have them this way. You still have the military ones you would design even in a normal game so this is a non-issue really imho.
The second is the Shipyards. For obvious reasons commercial ships are bigger than the military counterparts, so I have SM on to adapt Naval requirements per 1,000 tons. The big shipyards are not allowed to build anything that contains weapons besides CIWS.
There are few small things you have to work on the shipyards side as unfortunately there is also a difference in costs and time for expansion. I will one day though work with standard Naval Yards, probably just gifting myself the first 10,000 tons.
Also, you have to manage properly the tonnage if you do that. 80,000 tons of freighter can be quite expensive to maintain otherwise. Eventually, civilians play a huge role in this game, which is why even my commercial ships are very small compared.
