Playing with all DLC and patches. I am not a great player. I don't play very often and when I do, I play prince. I decided to try King. I was basically in last or next to last in most categories until modern times. So I basically built some bombers and was able to pretty much kill the AI militarily. Even though they were ahead of me in technologies, no one built any fighters or anti-aircraft units to counter my bombers. They also did not build much of a navy either, but at least they had some ships. Disappointing. Do they ever build aircraft?
