Structures are intended to be a flexible construct able to reflect all possible objects in the Coindroids universe.
As examples, our classic Crab Legs may be a mobile structure, with battle systems, defensive systems, and an ambit of Land and Water. A large immobile Land structure capable of storing other structures could be a warehouse or a fence.
The key to this system is that while it is easy to create schematics with one of two of these features and attributes, the more specific you attempt to design the more effort is needed to find a valid structure that meets those needs.
