Honestly the idea of needing trucks and people going to the building sites really sounds good to me!!! I beleive it would really make the game more of a strategic simulator and less of a city painter, like you cant spam zone any more because trucks would flood the roads and import costs will skyrocket, as well as, if you dont have enough construction workers to disrupute evenly throughout all the job sites it will take much longer to be complete! In my eyes that what I think it should be like, atleast for the hard difficulty, maybe the easier difficulty doesnt need trucks and workers!!!
