Talamius said:NPC villages can be really cool when done right. Not sure if it is updated for 1.6.6, but Millenaire was an awesome SSP that added full NPC villages with their own economies with NPCs that would harvest and mine on their own and build. Hopefully that is the direction Notch is going.
It is updated and it is pure awesomeness. Now you even have reputation with the different villages and that affects the trade system. I really hope Notch gets some inspiration of that mod.
