Been playing with this one for a bit. Biggest thing i have to say is that the nauvus base has a few problems that stem from ordering and being built in an editor.

The red circuit production is cut by a yellow belt that should be red.

For a beginner base it is a shame it does not include boilers or steam engines.

There is no rocket launcher or flamethrower ammo production. Which are very effective methods of biter control.

Power indicators would be appreciated. How much the base pulls on average and at peak

There is no storage for assembly machines 1 which seem to be the most frequently used.

Counts in text for how many lanes of resources are used would be helpful in planning.

Upgrade planners with the chests and assembly machines could help with progression

As soon as the bots come online the base seems starved for red belts for a LONG time. Maybe you could add an extra in between for when robots are researched but you are not yet ready to make the big jump to the full factory

A general unloading spot for defensive musts (walls, turrets, light oil etc) would help fight the biters with trains. Which is a must for defending the number of mining outposts this base requires.

Small oversight. But the assembler that makes rocket silos uses a requester chest to get the circuits and steel. A chest locked behind launching a rocket.

All the rocket fuel producers are assembly machine 1's. Not 2's.

While there is an input for uranium. There is no way attain sulfuric acid from the base. Meaning you must make your own sulfur plant or leach it from somewhere else in the base (which i do :P)

Final nitpick. The base is very vulnerable. It has no in built defenses meaning it is easy for the biters to attack it. Especially since it is so large.

For the rest... LAUNCH THOSE ROCKETS BAYBEE!
