By describing violence in graphic detail. It’s as old as Homer: “Running behind and overtaking him, Meriones hit his buttock on the right side and pierced his bladder, missing the pelvic bone. He fell, moaning, upon his hands and knees and death shrouded him.” (one of many, many gory deaths) One of the definitions of graphic (3rd per Merriam-Webster ) is “marked by clear lifelike or vividly realistic description” or “vividly or plainly shown or described”, and that’s what they mean. As to why Google Play thinks it makes sense to censor graphic violence in apps, I don’t know, but I think it’s foolish, lame, and stifling, and makes me shy away from developing games for mobile devices. But I wonder if you can’t just set appropriate flags or something and get it published acknowledging that it has violence in it.
