I wish they didn't tbh, that can end up making the content less than stellar just to satisfy personal headcanon
I think it has to do with political correctness, some people say that they don't like sex or any depiction of it, others don't like so called 'mixed race' etc. Some don't want roamnce in their games at all, they can't even deal with the thought of it being in there even though it is optional. Look at how many people complained about the Cassandra romance (a surprising amount) just because her breasts were shown. People were saying how they dislike seeing breasts and all this stuff, they said that there should have been an option to cover them up (ridiculous). On the DA confessions page, one person wrote something like: 'When I did the Cassandra romance, I was not expecting it to be so explicit; I can't believe they went there...' as though Cassandra's romance was some kind of hardcore porn scene--all it did was show the naked top half of both the Inquisitor and Cassandra.
Many gamers can't seem to handle any mature content, Bioware knows this. I think Bioware leaves some of these things open to interpretation so if they get a bunch of complaints from people with 'wounded sensibilities' Bioware just says "well it's open to interpretation, you just take your offence, and believe whatever you want to believe." Yes it is ridiculous, but that is what political correctness does, it censors, and makes everything silly, silly in the way that authoritarianism is silly (some will get that). Also, Bioware gets to remain aloof enough so that they never have to really defend their depictions. They just flatten the landscape and say-like the Fiddler on the Roof song, just replace 'tradition' with interpretation and God with consumers-"how do we keep our balance? That I can tell you in one word: Interpretation!" lol "Here at Bioware we have interpretations for everything, how to sleep (shows scene of someone about to close eyes, but then cuts away) how to eat (shows scene of someone about to eat a cheeseburger, but quickly cuts away to black) how to work (shows someone gnawing on their keyboard) "is he trying to eat his keyboard, or is he trying to type with his mouth? I don't know, it is open to interpretation, but I have some headcanon on the topic and I'm sure you do too." One would think that ambiguity and interpretation are Bioware's two heuristics to life. lol
Honestly, the Cassandra scene is just as open to 'interpretation', because no sex is shown a person could say, e.g.
Orlesian Nobel: 'Oh my, I must spare myself the indignity. They did not have sex, they did not. They simply rolled around on the ground and got too hot, then afterwards they took their clothing off to cool down... Oh no, even that makes me light headed..." *dramatically faints* XD lol
Could this silliness simply be solved if people with their own sensibilities, that are so opposed to the mature content that is described on the back of the video game box, simply played other games rather than try to enforce their censorship on other people who are not put off by mature content?
There might be a materalisitc expalnation as well for why Bioware would want people to use their imgaination, rather than Bioware having to spend on more content.
