It would be great if you add a property that gives 1 diamond per that type of property per day.
Make it cost $10 billion and only buy 1 at a time with an inflation of 25%....
That would make it difficuld to be able to get mass amounts of diamonds yet allow us to gain a couple per day, more or less based on how many a player can afford to buy.
