But doesn't the leader of a civilization reflect when that civilization was at its golden age, or at least the peak of its civilization.
I find America & Russia to have very interesting choices of leaders, as Lincoln + F15 don't really go that well, whereas Catherine was good for Russia, but the Soviet Union was definitely their peak.
USA - FDR or Kennedy (USA's peak is end of wwII to present)
Russia - Catherine or Stalin (I think Russia's peak was during the Soviet Union)
England - Elizabeth I or Churchill. Or Nelson/Wellington. Infact, Nelson is a bloody good call. (Churchill was our best leader, but wwII was the end of our #1 spot as a global power. And what would our special unit be? a spitfire? or a commando! I don’t know, I think our UU is exactly spot on, but it doesn’t have as much impact on the game as it should have. A Redcoat Infantry of the Line (before Nationalism) or Zulu-esc infantry, think that’s enfield rifles? I don’t know!  )
France – Napoleon or Charlemagne definitely. For a UU, would be difficult, once again it would probably be an musket infantry, and the French empire also created the idea of total war, fielding huge conscripted armies (levee en masse), maybe a National Guard unit somewhere around nationalism. Or the ability to conscript Regulars from cities or 5/6/1. If it was Charlemagne it would be a Knight unit, maybe a Jousting Knight 5/3/2.
Germany – after thinking Hitler, I read up on Bismark, and it should definitely be him. The man was a genius, he used to plan 20 years in advance, and foresaw the first world war! But the Franco-Prussian wars were his main success, and the main thing that was the needle rifle, or another cavalry. But its hard to slot all that in, as Civ doesn’t really have step by step unit upgrades, its all big jumps! If the leader was Hitler, then the Panzer is spot on!
Netherlands – William is probably correct, but Swiss Mercs as their UU? The dutch, like the English should have an overpowered naval unit. As navies are difficult to put a game winning impact on the game, especially seeing the age of sail is so short lived, they need to be great at what they do!
Ok, I think my boss knows I’m not working now!
