Surprising no one, the ESRB has given Diablo III an M rating!
And, while yet to be rated in Europe, the ESRB rating may give some context to the game itself, even a spoiler or two. After rating it for Blood and Gore, Violence, the ESRB had this to say about Diablo III
“This is an action role-playing game in which players assume control of a mortal hero (e.g., witch doctor, barbarian, wizard) who must defend humanity from a demonic invasion. From a 3/4–overhead perspective, players traverse dungeons and use swords, axes, and magic attacks to kill a variety of human-like enemies (e.g., zombies, demons, succubi). Battles are accompanied by slashing and flesh-impact sounds, screams of pain, and frequent blood-splatter effects; creatures often explode into bloody fragments as multiple enemies are dispatched at once. Some levels depict burning corpses and dead villagers amid large pools of blood.”
Well to start off with, the succubi are back. Also, it appears there will be at least one ravaged village in the campaign, but otherwise, it looks like we’ll be getting pure, bloody, M-Rated bliss on our PCs early next year.
