Industry definition: Synonymous with “gritty” or “violent”, usually used to describe horror games or shooters (first- or third-person).
Real-life definition: The closest definition I can find to what’s above is this one:
characterized by or dealing with coarse or base emotions;earthy; crude: a visceral literary style.
Somewhere along the line the definition was altered and people started using it as they do now. I’ll admit that it rolls off the tongue quite nicely, but on top of the incorrect usage the word has become such a cliché that it people really need to consider retiring it. Who’s with me?
