I failed multiple runs in the endgame by either going bankrupt or not being able to take all provinces without trucebreaking and killing my country with it. This is the first that I completed one and it has the best time yet! You have to have a lot of luck to be able to take everything without trucebreaking. It's especially frustrating if Muscovy vassalizes Ryazan and Tver and ends the run after you've already played for over an hour :D

I wish everyone good luck who tries to beat this run but I can say it's not good for your sanity :D
