You cannot research all of the arts in every campaign - indeed, only in the longest campaigns with many bonuses to research will you be able to achieve this goal. Each art in Shogun 2 takes a long time to complete, making prioritisation necessary.
I have written this in order to provide a complete breakdown of the most important research (also referred to as arts or technology) to obtain during the campaign for each game. Welcome to this definitive guide for Shogun 2’s main campaign.
