I have seen it been done before, and I reccomend you do the same;
If possible, gather as many trustworthy people that you know will help you build the city, then make a public server.
Then set those people into groups to collect certain resources, then have them bring those resources into a chest near the build. Save your work and then close the server. Then, build with what resources you have. When you run dry, repeat the steps of gathering people, setting a server, and gathering resources.
I have done it on a much smaller scale. If you WILL create a server, we would be more than happy to help. Just make sure you have a checklist of who is coming so trolls and greifers do not ruin your project and a group of admins to kick a person who is not on the checklist.
First off I want to thank everyone for the insane amount of praise I received for this. Seriously I probably wouldnt have even started this without the community help.
I have decided to give out the save for now. I may finish it later on, I feel like once I go through some more projects I may want to return to this. But for now I'll let you guys explore it a bit ( and im sure someone will set it on fire).
Well when you start off in the world you will be looking at one of the most anti climatic entrances ever. Just hop in that mine cart in front of you and ride on down. Enjoy the purdy view. Ill just let you explore the rest.
Thanks alot guys, I hope to finish this one day, and im working on it off and on. I think just the massive size of this monster takes part of the fun away from it. If i make significant progress ill update.
I'm thinking that I will finish it, I started thinking of all the new possibilities that i forgot, lighting up the ocean with light stone, transportation through the ceiling by dropping mine carts. I also realize that this is lacking in structures, as it is mostly islands, water, and trees. so I need to fix that. Actually just writing this is motivating me, so i think you can look forward to a update.
You sir, are my Minecraft Hero. This is the most amazing thing I have seen in Minecraft, bar none. You lucked out on the world, it looks great, and resources aplenty, but then to uncover the chunk error, and to follow through with such a creative inspiration... Well done. From something unexpected, comes something amazing.
I feel I should send you a postcard, or buy you a kitten, or something. Tell you what- Pick a charity.
