This is in BTS. You are Hannibal of Japan. There are the standard 6 AIs, all aggressive (Boudica, Genghis, Hammurabi, Montezuma, Shaka, and Tokogawa), with random civs. Since there is just one continent, they will all attack you with huge SODs throughout the game.
The challenge is to win by conquest (space would be too easy). The AIs are allowed to win by any method.
Is this impossible? With a random map, absolutely. Your city will get pillaged relentlessly and there is nothing you can do about it. To make it sporting, I borrowed an idea from the Age of Ice scenario. There is a mountain wall isolating you in a small protected valley in the NE corner of the map. There is a single pass through the mountain. Hold the pass and you can develop in peace. Lose the pass and you effectively lose the game.
You also start will a super city location with 11 resources plus 10 flood plains. That may sound like it would make the game too easy, but you will need it against the dieties. The valley has copper, iron, horses, elephants, coal, oil, and aluminum so you will be able to build any non-nuclear unit.
