Troll post notwithstanding, a glaring problem with this is that there's a large number of actual triggers and people also come up with their own "triggers" in an attempt to censor content or people they don't like. If someone is triggered by rain at sunset, should we prevent that from occurring in the game? What about red shoelaces? Or maybe an NPC who looks like the guy who murdered their wife? If the game includes some trigger warnings, someone will notice that their (real or imagined) trigger didn't get included and raise a ruckus about it. Where should they draw the line of what's included and what isn't?

Another huge problem is the work of reviewing all the existing cutscenes for triggers. There's what, 50 hours of cutscenes? 100 hours? Plus all the possible interpretation issues over what actually constitutes a trigger.

It's not that I'm against the idea, I just don't see it as very realistic to implement.
