well soon you can start unlock them! i just finished the code for a unlocking script i have been working on witch will load in the beggining of a game what majors you have unlocked when you make a new world you will choose a major that gives you a buff that will make the game easyer in the early game! You can unlock more majors by doing different stuff in game. the first major you can unlock is about 20% chance of unlocking when building a house. Been removing some minor buggs and also added the nuke feature! if you think your town is getting boring just press the nuke icon and your city will go booom! just a litle fun feature :P
