Over the past few years I've built the Future City, including a spacecraft airport with the large spaceship,
a spaceship shipyard, an armaments and weapons shop, an experimental laboratory, a glass dome (village),
a radio telescope, a large automatic Indoor food factory, a large mine with a sorter,
a large automatic material sorting and melting plant, many underground tunnels and corridors.
The city is not finished (such a city will NEVER be finished!) And open on one side.
So you can expand and design it according and use it to your ideas. I hope you enjoy it ...
To get the look as in the video you have to use my "Future-Space"resourcepack with Optifine(absolutely necessary!)
