So apparently, I can theoretically capture North Pole and Penguinopolis, and wait until I have huge amounts of cash from the revenue of Zomb-aid and the ice cream, get all the revenue upgrades, then the other upgrades, then profit.
Three tanks moving in, last mission. Morale is high, and I'm literally one trench away from victory. One squad dies, morale goes from 80% or so down to 0% and everyone on my side surrenders.
Auschwitz 5-Star Luxury Resort: 1000/1000 guest rating on average (sometimes goes a bit lower, but mostly maxed out), monthly revenues of $500,000, every room a presidential suite, 12 spaces across, then a 3-wide section of elevators, repeat. One of the sections is devoted to things like laundry (9 laundromats), cinemas (4), 3 pools, 4 arcades, 3 restaurants, two bowling alleys, two discotheques, and 6 receptionists on the ground floor (6 on top floor)
Sounds legit.
