I am building a ity on survivalcraft, its a bit better because there is more items you can use. Anway, the world the is Rivulet City, the seed is 888, the game mode is creative, the enviorment behavior is static ( no animals ), the terrian type is flat. Just saying you have to pay about 2.00 for real game (not the demo), and I would love anyone with a creative mind, but if your not good at building houses or building you can always help with the small details ( traffic lights, roades, etc). The smallest details are the most important. Anyone above the age of ten will do. Thanks, if you would like to help.
