I am someone who greatly benefits from a specific type of trigger warning, and I appreciate all corporations that take the time to implement them.
When I play D&D, I usually have a list of trigger and content warnings for specific topics that may arise during the campaign. The generic 18+ or similar warnings for the game are very broad, covering everything from nudity to extreme gore, making it difficult to understand what exactly is involved. A list of specific triggers is much more helpful and is not as lengthy as some people might suggest.
Additionally, there are other ways to incorporate trigger warnings into the game beyond pop-ups or Steam descriptions; for instance, game mechanics could include companions warning players about certain topics or books providing specific details.
