Quoted from cooked71:Another theory: By adding more pins, it becomes more of a destination for more potential customers who also spend longer in the room because of the great collection. Therefore, the size of the room effectively grows.
In theory that is...
Sure, but you still have to find the amount of money in that room.
Let's say that Pinball Polly's has a really deep collection of 75 pins and that brings in people from a 1.5 hour drive radius because it's known as a pinball "destination". Every weekend night the pins take in $1000.
If they double the number of pins to 150, will that double the number of customers? No.
Will it double the distance people will drive? No.
Will it double the cash take? No.

Doubling the number of pins will add a small amount of additional customers, but not enough to justify the additional maintenance.
