The historical attainment of Mongolia is defintely hard to achieve. Somebody can really finish this without going to the americas. Post it here.

I've collapsed within spitting distance on the old version. They theoretically got a little easier - i'll check it out at some point.

Mine either.

Maybe the keshiks will pass on this place: Khyber pass.

Done on monarch 600AD start. 3.13 with only 10% of map required.
china declared on me, so i got the bonus keshiks. I took china and korea, razed hanoi to make room for my own city there and made peace with khmer.
Karakorum,Turfan, Ulan Ude, Khanbaliq and Jinzou finished barracks and ger and just built keshiks afterwards. constant whipping and chopping.
Around 1380 i turned west, down the silk road, took smarkand, qhandahar and persia from the arabs. collected some troops and attacked turkey. first razed baghdad and two cities flipped, took all the left cities, except jerusalem, where he had all his troops but it became independent so i left it. took the single japanese town on the continent. took constantinople and athens to make more room for my culture and hit 11% at 1500AD -> Golden Age and became stable again. Split my troops, half went to india and razed the indian towns except patna. (i dont like razing holy cities even if its nonsense when going for uhv). My other troops razed the arabian peninsula leaving mekka where he had lots of troops... hit uhv in 1530AD with 11813 points. Which is much lower than my persian win, but anyway :)
Notice i used slavery/vassalage throughout the game. teched calendar for happyness resources and engineering for speed on roads and just build keshiks (and longbows for defense) but no siege weapons.

Oh. Yeah. The new version was easier. The previous 12% is reduced to 10%

Keshiks are truly an asset to mongolia.

very impressive, wr4th.
I'd love to see a game with you against Whitefire or Abegweit.

Btw, will you write the strategy? http://wikirhye.wikidot.com/rfc-mongolian-strategy

As you wish :)
It's in the strategy section.
