I’ve been waffling all morning about whether or not I should enter this discussion. I have no strong feelings about the subject itself (so I was inclined to stay out of it), but I also do like terminology that’s precise and clear and correct and (ideally) simple – so for whatever it’s worth, here’s my two cents.
It would be nice if whatever terms get used for the three factory/complex types could immediately and unambiguously express how big they are relative to each other when the three terms are seen side-by-side, and preferably even if they’re seen in isolation. It would also be nice if the chosen terminology didn’t deviate too much from established A&A practice. The official rules call these units Industrial Complexes (hence the handy acronym IC). The term is, in my opinion, conveniently generic (potentially covering everything from a single factory building to a whole industrial city), in the same way that IPCs are a generalized and abstract representation of gross domestic product rather than dollars. On the other hand, the IPC sculpts that were part of the older games look like a single factory building, not like what we’d call an “industrial park” today. Their design, however, is a conventional abstraction for industry in general (see the examples below from Frank Capra’s Why We Fight films), so it can plausibly stand for more than just a factory building.
By the way, just to toss in an extra item from everyone’s favourite unofficial source of information, Wikipedia’s view on the subject is that:
Industrial complex may refer to:
A factory or collection of buildings relating to industrial production
Military-industrial complex, the term referring to a close and symbiotic relationship between a nation’s armed forces, and its private industry.
Anyway, taking as a starting point LHoffman’s comment that…
“factory implies an isolated and singular building where production takes place (i.e. small, focused and not widely developed). An Industrial Complex implies an undefined number of multiple production elements grouped together in a large and expansive conglomerate.”
…my suggestion would be to use these terms:
Major Industrial Complex
Minor Industrial Complex
Single Factory
