I always opt for a robot based base, but without the "spine" of the Main Bus the base easily becomes cluttered and disorganised. I ended up slapping roboports left and right to cover random holes in the network (where important chests just happened to be

Now I have played 2 campaigns with my new City Block structure and I absolutely love it, so I wanted to share it here

The idea is simple:
A City Block is the size of 4 Roboports and includes roads, power poles, lights and a big area for building a modular area.

I generally have a number of different types of city blocks
* Inbound logistics (Trains and storage areas)
* Smelting and Processing (more of these are needed with Angels mods and Yuoki Industries)
* Power (Solar/Accumulator or steam powered)
* Production (Oil, Military, Circuits, Robots etc)
The album illustrates some of my different types of City Blocks.

It is incredibly easy to expand the base by simply stamping down more City Block blueprints and filling them with what is needed, such as in the Africa base below:

I have introduced this is my Yuoki Industries Lets Play (link in signature) and will continue and expand it further in my next season 5 starting soon
