I was wondering if I could do this, and decided to give it a go. I used settler difficulty, because I'm not sure if it would be possible on any of the higher ones with my skills. I'm sure some freak out there has already done this on deity.. Also I reloaded multiple times during this, because I figured that playing on settler is already cheating so why not go for maximum cheese... Naturally I used marathon speed. I play as the mongols, don't know if some other civ would be better suited for this, probably... First I warrior rush China and India who are still undefended at this point. Persia was a bit tougher nut to crack because he already had 2 warriors at this point and the random number generator kept screwing with me, so I admit I reloaded few times here. But then: I pop a settler from a hut right next to Europe, so I'm able to pump out warriors quickly. Arabia, Egypt and Greece all have only one warrior and fall quickly. I start battering Europe with Axes and Chariots, but then I realize Tokugawa is also on this map (I honestly had forgotten about him..): Oops... Well, no big deal, he's on his small Island, I can take him out later, right? I take out the rest of Europe by 1000 BC: I leave my original capital to the barbs so my palace gets moved to Europe instantly without me having to build it. Then I make one coastal city so I can prepare for the Japan invasion. Then I build the great wall so I don't have to deal with barb crap. In retrospect I should've made at least one more city next to it, and I probably should've retaken Karakorum at some point. Sending few keshiks to take out Mansa Musa: Now it's just a matter of racing to astronomy ASAP. I build the mids, the great lighthouse and all the good stuff. I bulb machinery 360 BC, self tech optics, and Oracle astronomy at 310 BC: 30 turns left to invade the new world (and Toku). Is it doable? We'll see soon! I load my keshik army to galleons, plus one settler so I can make a canal between the Americas, so I can get to Hyuana. Roosevelt falls pretty effortlessly at 210 BC: The Atzecs capitulate with one city left so I save one turn. Now after the Inca: The Incan empire is gone at 20 BC. Will I make it?! Spoiler : Unfortunately no, Tokugawa proved to be too tough for me. I should've focused my attention to him earlier on and If had remembered he was in the game, I would've played a bit differently from the start. Maybe I could've switched to universal suffrage and bought some troops? But overall this was pretty fun and I'll have to try it again some time. Definitely doable at least on settler. Have any of you done this with any difficulty?
