I don't really see the need to draw a line there, I feel the game is quite a bit more grim at other places already. The game just needs to acknowledge that working prisoners/slaves are a morally ..."ambiguous" thing. For a faction that sees itself as virtuous they should be a illegal "commodity".
There's being grim in backstory/text, and then there's tying that sort of stuff directly to mechanics. I'm less comfortable with the latter.
(Yeah, sure, you're also shooting lots of people, but you're shooting "ships" and the people are kind of swept under the rug. If you bring that front and center, it gets weird.)
Anyway, I'm certainly not opposed to mechanical things being grim or unpleasant. What I'm sure I don't want is for "run around enslaving people" to be part of a core playstyle. You'd have to really handle it well and make a game be about that. It's not something you just want to throw in casually.
Other stuff could work here, though. Some crew just shows up in the salvage screen? Sure, why not. You get a message from an escape pod and X crew offer to join? That works too. (... and then they steal one of your ships and run off. If you can't trust desperate crew you 've picked up from an escape pod after you've shot their ship out from under them, then who can you trust?)
BTW, two typos in the Recovery Operations text:
Base chance to for disbaled ships to be recovrable
I also feel the explanation is a bit roundabout, with first making a general statement and then contradicting it immediately ("Base chance for disabled ships to be recoverable is 25%, or 50% for your ships."). Since ships from allied fleets are not recoverable it is also incorrect.
Why not just say: "If disabled, the base chance to be recoverable is 25% for enemy ships, and 50% for your ships. Weapons have a 25% base chance to be recoverable from enemy ships, 50% from your ships."
Thanks! Updated to mostly match your suggestion, it was indeed pretty awkward.
I disagree, slavery and forced labour has been a part of the human experience as long as our species is old. It still happens today in the tens of millions, its just going on in the islamic part of the world.
In the west its essentially illegal commodity even though we dont really have a philosophical argument against it enforced on many levels of society. (Think certain forms of taxation, prison labour, propagandizing populace etc etc)
I do agree it shouldn't be done as a cheap throw in but that applies to most anything, it should be done with some thought put into it, essentially it needs to work but not so good that it becomes a near necessity.
Heavy faction relations penalty for example would be a rather strong penalty against neutrals doing that.
