But see, your suggestions here are actually new content. Exploring and taking missions INSIDE other structures. New ways to interact with things. And that's cool if they are added on like passenger missions were...an additional mission type. But beyond that type of addition, things such as interiors on our own ships, crew on our own ships...our ships are currently fully manageable, virtually instantaneously, by a single pilot from the cockpit chair. Any changes or additions there will be not much more than time sink busy work.
Even examples such as being able to manually repair things so one wouldn't have to take up the slot for an AFMU. Well, that is something that would be relevant mainly only to explorers, and there are very few ships any more that are that slot starved, and the biggest use explorers have for AFMU's is repairing FSD damage on Neutron Highways...that are taken because of the fast travel times. So I am not sure there would be much appeal for manually repairing mini games beyond the occasionally novelty.
I've said this before but almost everything you say has been suggested sounds dull.
So you won't see me disagreeing with you. I'm just saying that it takes a few seconds to think of exciting reasons to do new stuff that gets us off the chair.
And we'll need quite a few of those to become reality if the work required to build ship interiors can be justified.
I'm not saying this is you but the common objection against interiors goes something like:
"fixing modules on foot? Sounds dull. It's a no from me"
The logic of which is nonsense. Ship interiors =! Fixing our ship. But that's the reason it's "a no from me".
Might as well be a celiac that says "go out for dinner? And get served bread??? Not for me!"
How about we don't order bread?
"No! Bread is served at all restaurants and everyone orders it! No one could possibly want soup! Not for me!"
Just naysaying for the sake of telling everyone they don't like fixing their ship on foot. Yeh, I reckon most won't.
So how about ship interiors has nothing to do with that?
