I'm pretty certain i'm just regurgitating what everyone else here have posted. I'm a brony (who would have guessed?) and as such i enjoy the show and it's theme. But just as easily, i enjoy pieces of graphic, adult entertainment (Violence, Gore, Blood, dark humor...).
I played all sorts of violent games and franchises, Fallout (the series being a personal favorite of mine), Kingpin: Life of Crime, VTM: Bloodlines, GTA, Call of Duty, Unreal Tournament... the list goes on and on. Iv'e never had a problem seeing high levels of violence. I started playing some of these and more when i was 6. I suppose that means i got poor parenting, but whatever. I never had problems seeing death, violence and gore on screen.
I don't think a lot of others really have a problem with these kinds of games. It's a question of taste, really.
