This is just a world i made when 1.1 first came out, and i went nuts with creative mode.
I created a small army of machines (Screenshot)
I created a village surrounded by walls and protected form the menace outside.
And i created an industrial paradise, fixed on collection of ores and machines of war.
Enjoy the fruits of my creation.
It's not a very big map, but just enjoy what little details i put into it.
