Trust me. I have bank-end experience with games like this. There's no way money "earned" from it is a problem.
These generate cash like a cow. Usually because small micro purchases add up fast. Like I said I've spent over $100 USD in a month many of the purchases were .99 4.99 and a 9.99 here and there. It happens because you don't know your commit level to the game until after the initial spend.
So its a mega cash cow and that's only fair. It's a masterpiece and the founder and devs deserve to earn big from such an amazing and in-dept game.
But what they did today will KILL revenue. If they don't reverse this in the next 24 to 48 hours. Then, just watch, they will when the begin to notice the drop in overall $$$ and be forced to.
At the end of it, small micro purchases is where the BIG earnings are at. Crowdfunding. But with these prices they are slashing the base to probably less than 5% who can afford this and the 1 or 2% who will actually stick around and generate them income.
Devs, do yourself a favor revert this.
Encourage micro purchases. The range should be 1 to 20 tokens max for drivers. Or just go back to the old system. It was not broken. Apply that same old system to the Offices for staff and your done.
Don't over-complicate this game please. If it takes more and more time to manage. They will also be a massive hit to one of the biggest selling points... Time management.
