But...people are saying it's impossible to build a big city without mods because traffic will be horrible and you get deathwaves and industry breaks down etc. etc.![]()
I believe over 500.000 is easily achievable in Vanilla. I'be heard that according to CO they targeted a 1 million citizens city, but I don't know what the actual game Cap is.
The main problem is not complexity but game slow down. Currently this city takes between 10-15 seconds for a single in game day. At this rate it takes about 1 hour to populate a few city blocks. I had to leave the game running alone for several day to fully populate the 9 tiles. And a waiting game is not fun at all
