War Chariots AND Gandhi as the closest neighbour?
I still opened with a worker to get the corn farmed asap and start roading towards the target. The start was sort of awkward for the opening tech path with Animal Husbandry being a top priority but no actual tiles for it. So I decided to actually go pottery to get a couple early cottages up. Worker spent his downtime prepping war roads.
Built a second warrior and had them both hang around Gandhi's borders until a worker showed up, which was immediately stolen. Horses pop in the capital which makes this all too easy. Mining->BW->masonry is the tech path. With a lot of early unit maintenance and capturing cities more distant than we would settle ourselves, very early cottages I think is an ideal move.
One turn after 2000BC I capture the first lightly defended city (bypassing Bombay where Gandhi is stacking his archers):
Then Bombay, which will eventually be my bureau capital for obvious reasons:
Sometime around here Gandhi moved his fearsome stack of 5 archers into the open, which I killed at 90% odds. Very thoughtful of him. Then Palipatutra:
At this point I took a ceasefire because I needed to heal up/build some reinforcements, and Gandhi had stacked a good number of archers in his capital (7 or 8) and probably would have been close to a dozen within a few turns. That would have required around 20 WCs to be safe. So with a ceasefire I know that Gandhi will move some archers out to explore and also probably escort a settler (which he does).
I redeclare and take Delhi with only 4 defenders, one of which wasn't fortified:
Now this cost me a diplo hit with Isabella (the original declaration didn't because it was so early), but she's a religious zealot and adopting her religion will more than make up for this. Joao will get to pleased eventually with Hereditary Rule (his favourite civic), and Darius you don't really have to worry about when you share no borders. I then eliminate Gandhi completely by destroying his just-settled city (which I re-settle a few turns later. Buddhism is adopted which allows me to trade aesthetics for alpha (with a couple turns put into it) with Isabella, and then broker Alpha to all three known AIs.
A nicely placed barb city is taken in the nick of time, with one defender left:
And with one more settler between that city and my capital I'm at 10 cities all with very strong land. Expansion is over and economic recovery is in full swing. Lots of fail gold along with the gems mine (couldnt mine the second one til I traded for IW of course) and early cottage spam got me through all the way from writing to currency, and even to Metal Casting. Self researched that because a)it's a great tech in itself b)none of the civs I've met have it, and c)a Great Artist was born in a far away land, meaning music is less attractive. It opens up this trade:
This is a good trade for several reasons. Happiness is far more limited than the number of good tiles I can work (particularly with cottages spam in 4 of 10 cities). HR gets me a big diplo bonus with Joao, who has a different religion from me and we now share a bunch of borders. Organized Religion means I can spread happiness to the 6 of 10 cities that don't already have buddhism and also means huuuuge amounts of fail gold from repeat building the Moai Statues and the Epics. A total of +200% hammers with the bonus resources, Industrious, OR, and a forge...this can win you games, folks.
It's also a safe trade because one turn later:
