I read this on Discord the other night when it was republished - and there are two parts that make me sort of wonder:
1) I don't see how violent content can be prohibited when City of X is mostly about combat - that is the very definition of violence. I realise we have the PG-13 version of violence with no blood, but fighting is fighting.
2) "Sensitive" is a reeeeeaaaallly fluffy word - what is sensitive to one person, is completely irrelevant to the other and usually this sort of thing is judged by who feels offended not whether said offense makes sense or not. In City of X we have the Fifth Column (there was much rejoicing when they returned) and although we again have the PG-13 version of things, they ARE Nazis! True they are not building extermination camps in Boomtown but I am pretty sure Nazis still register as a sensitive subject in many places.
So basically, I cannot see a way in which the game itself is not a violation of the Content Guidelines unless there is some sort of implied grandfathering-in of anything already IN the game is ok, but new content cannot be violent or sensitive?
Both of these are terms of art with fairly specific legal definitions:
"violent content" means graphic, gratuitous depictions of violence, injury and death, like describing in depth someone being executed by decapitation or showing a picture of someone holding their guts in their hands as they bleed out in the street; the kind of violence in CoH is "cartoon violence", where nobody is bloodied or permanently maimed, injuries are abstracted away as a missing portion of a health bar, enemies are "defeated" instead of killed, and defeats are represented by comically tumbling away and fading out
"sensitive events" means mass-casualty events, large-scale tragedies or especially heinous crimes like wars, natural disasters, terrorist attacks, spree shootings, plane crashes, child abuse, rapes and so forth; "the Fifth Column" aren't an event, and the game pointedly avoids talking about any specific real-world Nazi beliefs or war crimes, leaning much more heavily into a comedic "creepy guys in Hugo Boss uniforms with a wonder-weapon obsession" depiction. In my opinion this rule is primarily to give the GMs grounds for telling people that they can't name characters things like "Eliot Rogers" or "Touchy-Feely Priest" or "Missing Malaysia Plane".
