Yeah, I am sorry, I thought it said billion instead of million. My mistake, however it still can be very close, like said before, it may be $999 million dollars. That is a lot of money, and a new country doesn't have to cost billions of dollars. It could be cheap, if it was built like Scotland or if it was like Festa Italia, small and with small flat rides and games with shops.
However they can do renovations, the drop tower, a roller coaster, and a new country as long as it all costed $999 million or less. If the drop tower is only $15 million then a coaster could be $25 million and renovations could cost up to a near $45 million which leaves $15 million for a new country. See, it all fits if you squeeze in the numbers and be conservative with what you have, depending if you theme properly. Too much theming is bad, but so it too little, and so theming for a tower really doesn't have to be much so they can save a few million off of that.
