Quick is so much better than Standard as a game speed it's not even funny.
Ended my second game, this time on Emperor with Scythia, with a pretty impressive Civilization style finale.
Started near Japan and did what Scythia does, overran it when it only had 2 cities and I had a flood of Mounter Archers, then Spain declared war on me and I ate it piece by piece.
In the meantime Sparta ran far ahead Tech wise, but I used my numbers and ranged options to just take one city at a time without taking many losses, when I ate enough to rival them in tech, I started building my nuclear power up. And that's when lategame strats started.
Just used all my Helicopters (which are light cavalry so they are really easy to come by for Scythia) to run in after nuking a city, taking it at the price of a single Heli.
Did the same for all their cities, then built up enough nukes to basically hit all the capitals of all the civs at the same time, taking a Domination victory basically in 2 turns from having 4 civilizations still against me.
At that point I could've easily gone for Science victory as well, considering that my production capabilities were overpowering.
I guess Immortal is next.
