I agree.
Thats why its even more important to give civs everyone knows about traits that we all know them for? imho
In your case with England and Germany, I suppose the devs were going for England's naval power, which was quite remarkable at its height and one of the reasons why England was so successful; in the case of Germany, I suppose quite a number of people with a casual knowledge of history know about how the Germans were famous for being a sort of "other" to the Romans - they fought against Rome and "destroyed" it (although current academia, so far as I know, regards this idea of Germans roflstomping Romans problematic at best and ludicrous at worse).
I think if we thought about it carefully enough, most civs could easily have several different potential UAs. Let's just take China, for example:
- China's known for its large population, so it could have a large population UA (sort of like India) or something related to agriculture
- On the other hand, those with a casual knowledge of history might know about its technological and scientific innovations particularly in the pre-modern era. Maybe a scientific UA would suit this.
- But then again, China was the cultural center of Asia, developing things like Confucianism that spread and heavily influenced neighboring societies like Japan and Vietnam to this day.
- Yet, China's also known for its
stereotypically zerg rush military achievements, if only through the Art of War - maybe a military UA would work.
- But, well, China was also a key part of the Silk Road and the reason why so much trade occured - because everyone wanted stuff from China. So maybe China should get a luxury resource or economic UA?
As you can see, at some point there's plenty of potential UAs that could fit everything. I guess what just happened was the devs had to eliminate some possibilities for certain civs because of balance reasons or because they wanted each civ to have a different and uniqe UA (no point in having 50% of the civs have only culture UAs). It is a bit unfortunate, and I can understand your frustration especially as I have been completely baffled at China's UA when I felt an economic or cultural UA would have suited it better. Oh well.
