I'd like more zombies that encourage long distance combat. Smoker does this, and it seems like the charger might too, but it's far too infrequent as it is now.
Also: Fiddle music, military bomb strikes, the bridge at the end of "The Parish", new characters, fiddle music, melee weapons (mostly axe, I guess) and fiddle music.
The "world" as you describe it, appear to look down on a lot of things. Be that video games, drugs, being a public school teacher or prostitution. Pedophilia is such a heavy taboo, as once it pops up in conversation, everyone immediately distance themselves from it, and those who don't, end up...
Being pedophile by itself isn't wrong. Not being able to control and committing crimes against children however, is very wrong, and one of the worst possible crimes not involving killing people.
