I just got this last week and have already played 3-4 games. I'm liking it so far since I really like the history theme and gameplay of setting up various action sets and combos. Maybe more ages could be cool too; Age IV and perhaps an Age V. My reasons:
However, I feel this game really needs more cards for each age. The game feels like it is over right about the time it begins.
The European monarchy (with a few exceptions), don't really die out until after The Great War, and I am sure thst there would be a good amount of people that could be useful from the early 20th Century; King Edward of England (who was a bit of an open-minded person, often seen at cat houses in Paris), Kaiser Wilhelm of Germany, who was quite an expansionist, wanting Germany to get into the beat in the (declining) colonisation, and setup several colonies in Africa. Perhaps a classic like Franz-Joseph of Austria-Hungary? The highly religious, but not so pupular, now saint (in Russia), Nikolaj ii (good for VPs maybe?), l am sure that we can also find some strong women, Nikolai's mother perhaps? Maria Fjordenova (sorry for my spelling; I mostly know her under her given name Dagmar), who had two orthodox churches build; one in Copenhagen (together with her husband Aleksander III), and one in Saint Petersburg (in memory of her husband who died of his wounds after an assassination attempt where the church is now build). Of cause we can not forget Queen Victoria (could be an Age IV, if an Age V was an option). Christian IX of Denmark could also be interesting; after loosing the Second Schleswig War in 1864 to Prussia, Denmark was crippled and poor, but he had many children where many were married in European royal houses (Queen Alexandra of England, the previously mentioned Dagmar/Maria Fjordenova of Russia, George I og Greece Thyra of Hannover), as well as Frederik VIII of Denmark, Prince Valdemar (who was elected to take the Bulgarian throne, but refused - married to Princess Marie of Orleans).
I am certain that if I get some time to dig into the houses, i am sure that I can find some interesting characters and fitting traits - maybe it would (or should?) be possible to expand/exchange some of the territories, but I am not sure what it should be, as I do not recall any interesting locations which could give gold or pierity value.
Just an idea, but I think it could be interesting ending the bloodlines as the European empires ends (Sure, France ends with Bonaparte, but the German houses (including United Germany), Russia, Austria-Hungary, and most others, ends around and after WWI, and I think it could be a fitting end of the game.
More cards could also work out; I am certain that more interesting personalities could be found.
