Here's my opinion on the matter, and seeing as everything will be going through me, I guess it's important.
1) In moderation.
2) That's thin ice, we are hosted by GS don't forget.
3) It it's gratuitously gross, well, I think not.
Basically, the stories should be about Freespace or Independence War, not about Jack the Shivan Ripper. Why? Because that's not what we/I am looking for. People don't normally speak like the guys in Pulp Fiction. Under stress? That's different. As for sex and gore, well...... try to keep those at PG-13, if you know what I mean. You shouldn't need explicit sex/death to tell a story, at least not the stories we're looking for.
Does that help some?
