How hard/possible it is to do a One Culture Achievement on my current game
Mughal game, 1697, half of the world already sunni (I assume). On track to WC on maybe 1730-1740s. Maybe less if I really try hard. Is waiting for enlightenment to maybe start culture conversion so I have net yet convert a single province.
Questions are,
Is it possible to do it before end date after I get enlightenment? Should I had start earlier?
What is the bottleneck of culture conversion (diplo mana or time?)?
Is there an efficient technique to use when culture conversion (like start spread out so you can get neighbor bonus)?
