Well i dont mind polling it but with so few of us would really be pretty pointless.
Basically we need a shortlist of about 3 but probably best 5. after looking down this thread we have:
Alexander (Greek): Aggressive Philo with Uu of Phalanx
Kublai Khan (Mongol): aggressive creative Uu of Keshik
Catherine (Russia): creative financial Uu Cossack
Genghis (Mongol): Aggressive expansive Uu of Keshik
Huayna Capac (Incan): Aggressive Financial Uu of Quechua (sp?)
Monty (Aztec): Agressive Spiritual Uu of Jaguar
Caesar(Roman): Organized Expansive Uu of praetorian.
Now if this is to be played on pangae war is inevitable and so i dont think we should play as a civ that doesnt have an aggressive trait with the possible exception of the Romans as their Uu is immense, i also believe that Russia's Uu comes too late in the game to be of any real use. I think that any civ's Uu that is in exchange of a warrior is also a bit pointless unless we are on a tiny map, so imo my top 3 would be Alexandar, Kublai Khan and Caesar, though in what order i am not sure.
