What I find really interesting is emergent behaviors from only a few lines of code. For example the villager children playing tag or the dynamic when zombies break doors and villagers are fleeing in random directions. There is no overhead “invade village behavior” it’s all a mixture of smaller reusable behavior modules. Another interesting aspect is the emotional relationship the player builds up with mobs. It’s worse to see a villager child being eaten by a zombie than a grown, so you want to protect the little ones. Also I really like small subtle behaviors that doesn’t necessarily add something concrete to the game but only atmosphere, like the new Iron Golem giving a rose to the children in a village.
