i've lately been trying to build my first mining city and i wonder if anyone got any good tips on how to do it properly and how to get the metal HQ upgraded fast.
so far i've managed to build a nicely sized city around the mines with 3 trade depots because they ship the products too slow at times for me. traffic isnt much of a problem in the city though the trade HQ isnt having a lot of progress towards its upgrade even with what i've built now. this is my city as it is right now:
what stuff should i focus on doing next in my city/what should i change?
and what are some good tips for moving onwards with it?
