cause I know and am going to achieve the best ending (where you keep all your promisses) without having any casualties

there is 5 simple steps

1: Buy every piece of property you can before the darkness shows up and buy each one right when you have enough don't save up for other more expensive ones unless all the property in the area is bought

2: put ALL of them for rent

3: Set ALL of it at the high rent

4: keep all promisses (obviously)

5:donate a lot of your money to the treasury

do this and you will have over the money on the second side of the treasury money and still have millions left over for yourself

IF YOU DO THIS YOU'LL HAVE NO CASUALTIES
