This will be really nice. Thank you for working on it and entertaining my suggestions. 

I think this button could be called, "Surprise Me!"   

Great work, @Lopess! 

For capitalization in the dropdowns, I think we can simply capitalize the words in the civ jsons: "Albion" is the ancient word for Britain. Sounds nicer to use.              

I was afraid I was mistaking the language. My apologies.   But great! I'll be happy to see what you come up with! I'm glad you agree with all the fixes and improvements.
