I'd like to watch that happen. Self-proclaimed "heroes" take out a giant spider and just as they're feeling accomplished, they hear the tearful farmer cry, "BESSIE!"

Or they try to kick some random Bugbear's butt and find themselves afoul of the very well-trained City Guard. "Why the hell did you attack Herbalist Fairweather?"

Could be a fun setting in D&D come to think of it.
