Isn't "realistic violence" more appropriate?
the example is «user shooting a gun at a human characters.»

vs. "Defined as fictional characters depicted in an animated film or a comic strip which do not look human." for violence-cartoon

or:
Fantasy Violence
"Defined as characters easily distinguishable from reality."

Fantasy for me is "an Orc" or "a Dragon", naval ships exist in reality, so it's not Fantasy.

For me doesn't count as realistic, Call of Duty is realistic, this doesn't look like a real naval battle or a real explosion, it's more a caricature of it, thus cartoon violence
