I've actually started playing again with 1.6 and been enjoying it so far.But man, they've really buffed the monsters. Skelli's are rapid-fire killers, and zombies are everywhere!
Not that I mind the challenge. I just hate the how the zombies can somehow manage to slaughter whole villages when I'm not around to protect them. Makes it really hard to go exploring or caving. Hopefully Villagers will start protectign themselves better by 1.7. Or at least stay inside til all the undead have burned
