While I get where you are coming from, as others have stated there is a rating for a reason. Its some places its PEGI 16, in Canada Its Teen. If it states There's violence and mature subject content, then take that to mean exactly that. I am all for every person of every colour and sex and all that including all their disabillities to play this game, how ever unless the game starts showing graphic depictions of rape and dark content like that (which they wont) I wont get offended or triggered by the content because I know its a Teenagers game in the sense its rated for teens.

As for warnings and what not. Maybe at the beginning of the expansion, not through out - unless its like "content ahead has strobing affects" even then.

But I am not for changing a story because it "spooked you." Warning sure (at the beginning of the expansion), change no.
