Not sure if intentional but the newpaperstand is flawed. I once had 300 newspaper stand and 300 Oil companies and it is more expensive to upgrade the newspaper stand.
I now have 400 oil companies and 344 newspaperstand and the upgrade price of the newspaper is triple of the oil company.
Other than this the game is awesome :D
i am stuck in India. My goal is to get a 10.000 dollar profit and i got around 200.000 and still rising well above the 10.000 dollar each day. so yeah...consider this a bug
