this is awesome.
however it will also end like other city tycoons. the bank has infinite money, and since we get money from just having a certain amount of bricks, people will get thousands of dollars in a very short time, not spending a penny, just using it to build, and as their brick count increases, so does their rate of money, meaning no one will actually spend it on the things, such as a clothing, fast-food, or a computer. we can just build multiple things can gain money through the bank.
i'm also aware you made quite ab it of money from your casino, but that's gambling, these people aren't going to become addicted and waste too much money on your casino, they'll come in whenever they have excess money, making casinos the only profitable business.
