Awesome work man, gonna test it now Edit: I tested it but don't see a big difference in growth rate. So do i need to make things like parks and stuff first? Edit 2: I tested it in a city thats alrdy long in the game. And i do notice a difference there. Though it isnt as high as i would expect. Building need about 2-4 days to go up in density. 1-2 would be better though.
