i am currnetly trying to force the game into having a mongol general as king ofpoland! this did require extensive cheating.

firstly bribing cost ~ 800 000 florins! I bribed two general and married them both to princesses (they have had lots of children by the way)

i am now killing off every heir i can get my hands on to try and force th game into accepting one of the mongols.

note- in my first campaign playing as the english i am sure that a general my princess married became heir to the thrown (but died before takiing it).
