Chieftain
Correct me if I'm wrong, but I believe technology costs scales up with map size to account for the larger number of cities (and hence population). In BNW, this upscaling seems to be too much on huge maps. In my current game as Venice (12 starting civs), I'm the tech leader, it's turn 370 and I haven't even started on Atomic Theory (my literacy rate is 72%). Despite civs like Poland and Persia having massive empires with fairly well-developed cities, they still can't match my tech lead somehow. Am I the only with this problem? O.o
