WOW i have only 1 million.How can this guys make to 6 million?

[SimilitudeB]

Yeah I've seen that 9.2 million! Crazy. Wish I'd taken a screenshot. Could have been a hack or system city but it looked normal enough. I also came across a city called Llama Slaughterhouse that seemed like a developer's city. I think it had about 5mil.

ive seen someone on 10.1M pop on there main, and theres just me with 3.5M lmao

It is not difficult to achieve 6 mil + if you play it strategically:

1. All main roads parallel to the beach

2. focus only on building EPIC buildings, forget about Paris, London or Tokyo

3. place only high pop specialization building strategically. Get only Washington monument, university, Ferris wheel, luxurious casino tower. For mountain: alpine vineyard. For beach: combination of pier and luxurious marina.  Ignore the rest. 

with above you can reach 7 + with a bit of luck.

My main city is 6.3+ mil , could have been higher as I started my road system incorrectly.

enjoy the game!
