Surely, the whole point of this game is an "adapt and conform" policy? No?
So... look at what you need to complete the next chapter and "adapt" your existing city to "conform" to the next chapter's policies and move on...
Just as
@Lisica (and many, many others) said! There are so many websites that can give you that information if you decide you want some "spoilers". If not, then build as your "quests" ask you to! It's as simple as that! REALLY! I mean, REALLY!
Personally, I have spent the last two weeks "adapting" my city to "conform" to the "Amuni policies"... and, now, I know that I can now complete this chapter without having to move or demolish any other buildings and still have 3,000+ POPULATION and 18,000+ CULTURE for the next chapter!
I also know this will take me around 3-4 months to complete! ^_^ Plenty of time before the "next" guest race! (HOPEFULLY!)
@Lisica is right and this really needs to be an "ELVENAR MANTRA"; "
DO NOT GET ATTACHED TO YOUR CITY!!"
I still mourn my "Wonky Walter's Big Top" as it gave me PLENTY "Culture", but it also gave me ZERO "Population", so it was useless to me!
IT HAD TO GO! It looked great in my city... but it was bringing my city down and
HAD TO GO! I still have a number of "CULTURE" high but "POPULATION" low buildings in my "INVENTORY" that I need to remove.. and will do when my "POPULATION" gets too low! ^_^
Since then, I have added many event "GRAND PRIZES" to my city that have increased my "POPULATION" & "CULTURE" and have helped me progress through the later chapters! But, proper city development (as you can work-out from various websites) would have helped three years ago when I first started with this game! So, I will say to NEW PLAYERS; do NOT feel bad when you fail you complete an "EVENT" as you will evolve your city (in time) to do so, but also acquire BOOSTS, GOODS, COINS and SUPPLIES to help evolve your city to be able to cope with future "EVENTS" until you're at a level where these "events" are too easy for you to complete!
TRUST ME; there are top 1000 players with 5-6 pages of "INVENTORY BUILDINGS" they don't need or want to progress their cities! I am one of them! ^_^
It's a shame that INNOGAMES will not give us "supplies", "coins", "goods", "guest goods", "sentient goods" etc for selling these buildings that will sit in their INVENTORY's... almost... forever!
TL;DR; patience! PATIENCE! Build as you do, do NOT worry about "RANK" or where you are in your "current chapter"... EVER!
