I understand the 9 tiles can be expanded to the full 25 tiles via modding. My question is can you mod so that the tiles are unlocked to begin with? Or does that somehow interfere with the simulation? Think if you started residential in one corner and industrial in the opposite corner. Would the citizen travel to the opposite corner for work? Or is there some limitation here. I'm thinking there is some limitation since they are locked to begin with and you must expand outward.
