Off course Michael the brave ruled a united Romania briefly also. He certainly has a distinctive appearance, and there is
a film about him which is very well reviewed on IMDb (though I don't know how well received it was by critics because it was only released in Romania I think). I haven't seen it but I am fairly sure the whole film is uploaded on YouTube. But Vlad III Dracula, even if only ruler of Wallachia, is clearly a lot better known, and makes more sense as a 'big personality' leader. He would have worked very well as a Civ 5 leader I feel; I can imagine his leaderscene with him sitting across a long dining table from you on a throne, with the room quite dark due to it being evening with light not coming in through the windows, but with candles by him casting a large shadow of him onto the wall behind. Bach's Toccata and Fugue in D minor would be his theme.
Also, I agree Dacia under a king like Burebista and Decabalus could be interesting. The fact it is an ancient Civilisation is alone enough to make it appeal to me. There is
a film about Decabalus as well. Modern Romanians are believed to have ancestry which is mixture of Dacian and Roman IIRC, as Dacia was conquered by the Romans and became a province of the empire.
Completely unrelated to Romania, but on the topic of very cruel rulers like Vlad, Phalaris the tyrant of Agrigento would make a fairly terrifying leader. Just imagine this brought to life in a game:
Though Phalaris is remembered as both an all around terrible person and an all around terrible leader, so his inclusion would be impossible to justify (although what we know of him could quite easily in fact all be false propaganda; there are outlandish sounding claims made about him such as that he ate babies).
Really ?
Victoria, Catherine de Médicis, Pericles and Gorgo, Trajan, Peter the Great, Isabella and Philip II... No, only the German leader is indeed medieval.
True. But another medieval European Civ ruler is Harald Hardrada, and so is Jadwiga (just about). And outside of Europe, we have Saladin and Hojo Tokimune.
Romania... Well, why not. We don't have any south-eastern modern european civs, if I'm not wrong. But Bulgaria or Hungary may be more interesting choices...
I know Hunagry and the Huns are not remotely the same, but was Attila not born in the area which is modern Hunagry? And didn't early rulers of Hunagry claim to be descended from him? I for one would like to see Attilla return; as with Vlad, he is a very iconic character.
