But from a more interesting perspective: where do you think OP such discriptor should be included? At the start of a hundereds of hours long RPG? At the beginning of act? Quest? WHen entering the location where such content occurs?
As I said a few times here now: I don't need a content warning, I'm pretty sturdy. This is the continuation from a discussion in another thread.
Edit: I would assume a general warning in teh description about the topics that might come up would be enough athough. Or an optional menue like in the gameplay video, Ametris showed a page before, where you can click, if you want content warning or not and if yes, how much.
