I think their should be new categories related to getting to certain populations or getting to certain levels of profit.

Currently, getting to certain populations (specifically Megalopolis) is the speedrun format for Cities. As for getting to certain levels of profit in terms of speedrunning, I could see it being possible. For example, how quickly can a person get to a weekly profit of $100,000, or whatever amount you want. Go ahead and make a video with your own version of whatever type you want and post it!

i want to run NoDLC, how do we get a new category
