And here:

Yup. I've read loads of comments from people moaning about it hitting you out of the blue, & saying "Oh, well, if I'd known I needed that much money I wouldn't have rushed through..." etc.

No sympathy for the moaners. It tells you as soon as you become King/Queen that you need 6.5million just to pay for the defence... And as soon as you start making Treasury decisions with Hobson, & Royal Rulings in the Throne Room, it's fairly obvious that "Good" decisions cost money and "Bad" decisions bring in money. Every load/save points out the current state of the Treasury and what the projected casualty rate is. Anyone who rushes through without building their money pile up, despite the obvious need for tonnes of money, & despite the ever increasing pace of the final "Royal Days" (each time a "Royal Day" ends, it jumps forward by an even higher number), deserves an empty Kingdom. Bit skint? Don't bloody go to the Throne Room then! Go off Questing, & make some money with property.

As you say, unless you invest heavily & make loads from shops & rent, you have to either be "Nice"... but let everyone die. Or be "Nasty" & end up a tyrant like Logan... but everyone lives.
