Saying that Diablo ever was a "horror" experience makes me laugh real hard. How old were y'all back then? Four years old? Because that's just about the max age at which Diablo might provoke minor emotions of "horror". Just like Warcraft Humans & Orcs and every single other Blizzard game in the history of that company it's always been very cartoony and light-hearted. And don't give me The Butcher. The name of that guy alone ("Da Butchaaaahhh") is so ridiculous and obviously meant in a satirical way that you can't seriously claim that that guy evoked any "horror". Or if he did I'd make sure you get an appointment with an urologist and let them check where your balls went or if you're one of those people who just has male sexual organs but is genetically a pussy.
Seriously, guys. Anyone out of elementary school would have to be a very strange critter to consider anything Blizzard EVER did as even remotely adult, let alone "horror". And now don't gimme the stupid 'M' rating. It only got an 'M' because of the succubus half-nekkidness. Can't have any titties in puritan America, of course.
