Emergencies’ frequencies are dependent on the game’s difficulty level - the more difficult game you selected, the more frequent emergencies will be generated. Also, if you choose a sandbox mode game, you now select certain criteria that affect your gameplay. This is all set ONLY at the creation of your game - you cannot edit it (in game) after the game has been created. Since all of this is new, (and the devs can correct me), I believe older games (specifically sandboxes) have defaulted to the easiest settings - no emergencies/animals, but oddly money and economics are treated as real.
NOW, the trick to changing this “manually” (without having to recreate your arirpot) is you can find the line of code in the game’s save file, and change these parameters yourself. If your save file is not up-to-date, first launch it normally in the game, and save it. Older saves may not have the lines of text we need. You can change these lines by browsing to your save game files (in Windows something like C:\Users\USER_NAME\AppData\Roaming\Apoapsis Studios\Airport CEO\Saves). Once you locate your save’s folder, look for the GameData.JSON file, and open it in notepad (it my linger a minute or two, as it is a hefty file). Then look for the following, at the beginning of the file:
“playerDifficultySetting”:3,“sandboxSettings”:{“sandboxEnabled”:true,“unlimitedFunds”:true,“disableEconomySimulation”:false,“disableConstructionSimulation”:true,“projectsUnlocked”:true,“allAreasUnlocked”:true,“unlimitedFlights”:false,“emergenciesDisabled”:false,“animalsDisabled”:true}}
PlayerDifficultySetting: I believe it ranges 1-3, 3 being the most difficult
All the sandbox settings are true/false, pretty self-explanatory.
Finally, I cannot vouch what this does for achievements, and I highly suggest backing up before anything as it may corrupt a save.
