I don't know if I missed it or what but there should be a menu like other games (Two Point Hospital for example) where you have options for Sandbox...So you get to choose how much money and CC you have (Unlimited is one of the choices), how fast you want time to go by, do you want everything unlocked or do you want to research it? Do your Animals become sick? Do they age? Turn off deaths? How often do they breed? Do your staff become tired? Yah know that stuff. I'm surprised they didn't provide this stuff for Sandbox.
