I guess one-two more years and you would have gone bankrupt:
-you get inflation from taking loans
-you get interest rates when taking loans, a lot of of time+money to repay it all
-it requests you to pay it back, if you don't do it in 3 years you get an auto bancrupcy
-this all causes revolt risk, conquered nations/provinces can become independent real quick
-mercenaries are needing a higher payment, and they don't get fresh recruits as your own troops, and an army only half its original manpower asks for the same payment as a full one
-with wars, annexations, and other actions you get BB ('badboy', it simulates how awful you are in the eyes of the world, if you do too much at once then the world gang bangs you
-an offensive style makes other nations less agrre on diplomatic deals and trade too
One good think is in EU3 the new claim system for provinces:
in 25 years you lose a core (claim) what you don't have
in 50 years you gain a core (claim) what you didn't have before
Claims (cores) represent the 'main body' of your empire, what is a part of it with history, culture, and things like rights by heritage.
Example:
Ottomans lose Constantinople to crusading Knights of St. John (unlikely but possible), if they can't get it back till 25 years later they lose their core on it and they get a new permanent Capitol somewhere else. After 25 more years (25+25) Constantinople and its citizens accept and acknowledge the 'right to rule' of the 'Maltese Knights' (in this timeframe Knights of Rhodos)
Well, I dunno if its possible to move the capitol in an other way, but if not I guess the knights could get their capitol in Constantinople (instead of Rhodos) eventually by losing Rhodos to someone else.
