I just played India using Tradition snagging the Hanging Gardens. It feels more powerful than before. The reason for this isn't because happiness is more prevalent. It was already that way in G&K and that relatively relaxed India's early game concerns. No, the reason I found India a bit stronger in BNW is because of Food Caravans. As always, I stacked the growth stuff - as much as I could get - anywhere I could find it. Fertility Rites, Feed the World, Maritime CSs - you name it. But this time, I also got to add +8 more food per turn to the capital via Food Caravans. In the Medieval period, this goes up to +10, +12, and so on. It feels really strong. The excess happiness from large cities didn't feel superfluous. Does this strategem, in fact, strengthen India in a meaningful way? Note - early game plays 3-cities Caravan opening, modified. Send out Caravans from Delhi to start, send them back once the expansion cities have Granaries. Alternatively, build HG in Delhi, Granary in Mumbai (strong hammer site needed), and then send Caravans from the 2nd city to the capital and 3rd.
