Well the game is utter garbage, it is completely broken. All aspects of the game are not fit for any sort of gameplay, maybe in the first few years it may have been, I was not around then.
Now it is just like any cash hoovering game on the net or mobile, it has pivoted to be solely focused on extracting cash whatever the cost or consequences, the customer is just an inconvenience that has to be interacted with to achieve the monetary reward.
Spending too much time, focus, energy or cash on it is a waste.
