Indian UHV:
Monarch difficulty, Normal speed, 3000 BC start. Finished at 1200 AD.
The three historical goals for India are:
1) Control the shrines of Hinduism and Buddhism in 100 BC;
You'll need to build the two shrines yourself, of course.
2) Build 20 temples by 700 AD;
Which means you'll probably need >=10 cities.
3)Have the world's highest population in 1200 AD;
Not a problem if you have finished 1) and 2) and survive till 1200 AD. (Right after that the Mughals will just pop right out of some northern city of yours though.)
The tech path I took was Priesthood->Masonry->Mathematics->Calendar, which is quite an obvious choice.
A few things to mention:
With my initial settler, I settled Takshashila 1N of marble. Dilli became my capital and Hinduism was founded in Varanasi. I chose Takshashila because it could provide much better production. Then build workers in all cities to improve tiles ASAP and build temples in Varanasi to work priest specialists. I recommend having 7-8 workers at the beginning.
Here's my city placement:
Pitikapuram is my 4th city because it is food-rich even before discovering Calendar. Madura was a barb city that I captured. (Wait until it grows to 2 pop or you'll be forced to raze it.) I intended to settle Hanoi but a early Kunming with Confucianism denied me of it, so I settled Angkor which later flipped.
About growing cities and building temples: One does have time to build granaries in all cities as the first building (except Varanasi, which will build temples first). With enough food and granary, temples can be whipped in time (even for culture pressed Yangon/Pagan).
About spreading religions: Varanasi alone may do the job well, which means you probably won't need to build monasteries in other cities.
The score is 10879. Finished at 1200 AD (of course).
Just mentioning: strijder20 previously gave a walkthrough of India and my play follows in a similar fashion.
