I find myself using a mix too, with older runners using frag and drek and more up-to-date characters or characters who are OLDER STILL using the real stuff again. So kind of like a shitdrekshit sandwich. One reason I never liked the old stuff, really (although it still makes me nostalgic) is because it really felt like a copout for ratings and to appease moral watchdogs and just 'soft', and I hate all forms of censorship, including self-censorship.
The official content uses a mix too, with characters like Bull. Speaking of which...
I tend to be a bit more "American PG" with my writing and playing... (So basically, Violence, OK. Swearing and porn, not so much). Just how I am.
My writing is very heavy on violence and swearing; while there is no "porn", there is other mature adult content (drug abuse, sex, etcetera).
Speaking of which, I kind of call BS on this. SRM 04-01 which you wrote is very very very very NOT PG. And is probably well in the realm of a hard 'R' rating, content wise. I won't say more because I don't want to spoil anyone.
I prefer the old slang. It set it apart from other games.
Mayhap, but it does move it closer to Battlestar Galactica, at least so I've read.
