I think I can quite easily double my money that i've put in, according to my calculations, once locations become scarce. This will be fun.
You are not the only one thinking this. There are others going down the exact same path now. In what countries are your cities, may I ask?
I have one or two in the UK, one or two in America, quite a few randoms spread in Finland, Italy, New Zealand, Australia, Croatia, Germany, Belgium.
So much fun finding these.
Btw, i've noticed that the website now has an enhancing option? This is exciting and new. How can I best take advantage of this new feature, and how does it fit in with the future of the game?
You can see if a city is enhanced by looking at the points. eg. Berlin is enhanced from 49 to 95 points here:
