Hi! I'm one of the developers behind this game. Thanks for the feedback! To answer your implicit question, the starting location is not randomised to provide the same experience to every player. The idea is for this game to be played in schools, so every student can have the same experience with different strategies and learn the importance of vaccination.
I do agree with you though. To add replayability, the starting location should definitely be randomised, or at least different campaigns should be available :)
