Game 2: Domination is still the preferred victory condition, but I took a slightly more science based approached on my second attempt since having knowledge of the map, I was convinced I wouldn't be able to take enough cities with early units.
I took the mongolian capital using war chariots and skipped composite until I researched education. I placed my 3rd city near ethiopian capital and placed a citidel then researched to dynamite to take the ethiopian capital.
Throughout the game I always tried to keep china and persia at war with either themselves or ethiopia or england. I managed to remain friendships with every civ throughout the game except siam and other civs after I DoW'd them and probably signed about 7 research agreements throughout the game, 3 with india.
Persia was the science leader for the majority of the game and I didn't pull ahead of him until I bulbed all my GSs around turn 260. I ended up anexxing all my captured cities after getting the social policy 'planned economy' and focused as much science as I could in preparation for the GS bulbings.
Persia was well on his way to a science victory and I decided his capital had to be my next move.
Persia was also on his way to winning a diplomatic victory on turn 308, so on turn 307 I sold all cities I could to him for gold to ally as many CS as I could.
I signed an open border treaty, and used 2 GGs the turn before I would DoW so my paratroopers would be in range of his capital, sold 4 of my cities to persia for gold so I could ally CS, next turn game was won.
I could have won by science victory somewhere a bit before turn 300 but I really wanted to win via domination so it made it a bit more difficult and ended up having to use a reload. All in all I thought the map was quite challenging and it was more difficult than most immortal games. Mainly because, except mongolia, all capitals were quite defensible or far away.
edit: sorry for the small pictures. I just uploaded to imageshack from the steam screenshot folder. If anyone has some advice I'd appreciate it.
