wow i just read this thread there are many valueble tips, the one most i catching is "dont build road on the capital city", and thx for the detail calculation on happiness its really turn off all the foggy thing inside my head on how to chop this problem.
Ok im going to report my progress,
im going well following the instruction from Kaltorak. First i follow his idea : disbanding worker.
Its instanly give me 8gpt and 20g in my pocket, such a relive.... But still i have a problem in gpt, its only give me 30 gpt margin or so, from -100 to -70gpt, and i only got 1k left on my cash. So i create market and bank in all of my city since i think it wouldnt hurt because it only cost tools. And i build several happy building for my bad temper citizen.
After several turn, while im preparing my army (not producing but relocating) to fight persia (i want dissband them but i feel un-easy if they go waste just like that so i gather them into battle) a great person pop up, look a scientist! But i need money, so i consume him to start my golden age, the result i got +100 gpt.
I contact Darius, try to bargain on some trade giving him all of my gpt and resource (luxury+strategic at all quantity), then he give me 4k, after i got what i need to survive for my civilization, i go to war (i read this trick just in other thread just yesterday, and it work, i feel a bit unfair about it but well i done it, what do u think? is it ok? i hope they fix this bugs)
After i go to war, im focusing on releasing city states and razing his building, the results after that i got more resource in some capital state and other city, and a few of my happy building are already being build, i got 20 happiness. After the war with persia, i go on with tokugawa with the exact strategy, i once reach 100 gpt and 18 happiness, it awesome. After finishing my war with tokugawa, waiting for few city that now being raze by my army, postwar my happiness is a bit down 2 unhappy, but yeah it realy dont mean a problem, and i got 300 gpt from my golden age. But the war goes interesting at the start, but begining brutal and less interesting at the middle, and boring at the closure. In the middle, it goes on shoot and raze in the middle, and at the end my opponent are producing billion of worker, that stupid, and i just go siege the city and raze, brutal and boring, seem chaotic and unstructure, my army goes seperate here and there hard to gather them back.
So the results, i win this game so far and im ready to advance in king level in the next new game (thx to u all i chop it only in hours) with more advance strategy that i gather from this room :
-i will try to focus each city with special capability (really really spessific) so i dont waste military building on commerce city etc, and i can safe lots of cash.
- i will try to use Piety instead rationalism, because i felt, in the end game, tech really mean nothing, and in my case i overlaping my opponent to much in tech but i cant really produce the high tech unit because the unbalance in happiness issue and economic issue. And 20% reduce in happiness is really what i want, it can give me 40 head of happy people for my country.
- In my early game, i do build road effiecenly but i connect it to all my city, it end up bit blunder, in the next game i try to more efficient the road by not connecting my city to the capital if the city already settle beside the ocean, and its really good idea. But btw, is it still work if my capital are not settle by the ocean? i just wonder if it still can connect the trade route.
- Yap, i still got a habbit from the early civilization game, i build what i plan on the city i settle or capture, like i start building forge in production city, or theater in cultural city, but now i will first settle the happiness foundation and commerce before i expand my city into the form that i want.
- I will... raze more city

i hate it but i got no choice, puppet make the building and population uncontrol (by info when "i love the king day" they are more focus in evolving population) while annex make it produce more

so yeah, play bit brutal, kick and rush, and its really not my style but what ever, i have no choice
i really want to say thx to all of u that contribute. This game becoming less :

and more
i will try to sumarize this tips and trick and post in new thread. Or an add at the front page so other with similiar problem like me can read it and avoid reposting.
Thank you.
i wait for another genius tips from all of u.
