[Escaflowne]

When I colonize planets I do several things:

Tiny worlds I classify as Storage Depots and place material storage facilities there.

I put a shipyard on any planet with 5 spaces or more, so I have plenty of production and repair areas available.

One planet in the system (preferably breathable) is the system capital, where I keep the Port and Resupply facilites as well as things that affect the entire system (shrines, training facilities, production enhancers, etc.).

If a planet has over 100% in a certain resource I have the planet churn out that resource exclusively. You'll need it at some point, you can convert it, or trade it. If more then one resource is over 100% I always go with minerals, or which ever is higher.

Anything else is research/intel.
