I agree. There are no point to pawn shops. They are not just a waste of space, but a waste of gold and silver tokens.I have to agree - pawn shops are pretty much worthless, especially since you are wasting space for something that's only collected once a day. Visa Centers, however, are a whole 'nuther story! Remove a section of road, place the visa center, activate it, and you have several thousand passengers by the next day. I have 4 visa centers and place them next to the quickest renewing passenger buildings. Or, if you're planning a big run of flights, move it around and gather passengers for as long as you can while it's active. I've gotten over 12,000 passengers in less than an hour, ready to send out maximum flights.
I love my visa centers, I would love them even more if they would count all the passengers.
Edit: I just want to clarify, I mean all the passengers that it is supposed to collect in the 1x1 radius, not all the passengers in my whole city.
