One thing that I hate about NPC villages is that, if you are helping them fight enemies and you accidently attack one, they all go crazy and hate you. You can no longer buy from them unless you kill most of them off. Maybe they should change that, and make it so you can't attack NPCs that spawn in villages. Ex - You walk into an Avian village, trade a bit, then night comes. You help defend the village from monsters but hit a guard. All the Avians attack you and you can no longer trade. Having a whole village attack you is kind of annoying, and it all started because of 1 person getting hit by you on accident.
They could just add guards and punishment to the game...(you could pay a pixel fine perhaps) if you are caught. They could also make a attack friendly toggle, for those players who want to be axe murderers....
Well, with how many monsters attack at night, you would probably have to pay a fine every second because you would hit so many people. I would like a toggle 'friendly fire' sort of button. That would make things easier, because if you attack over powered guards when you first start off, you're screwed. If you weren't able to attack them, it would make things easier.
