Just stumbled across this, though haven't played it yet. Your commentary explaining your motivation makes me think I would like this game. I agree that in the English-language world there is insufficient media speaking to this era and place, with most understanding about WWII being focused on Europe and largely ignorant of the complexities of Chinese resistance to Imperial Japan, or how the legacy of these events have stamped contemporary East Asian political economy.
Thanks in advance for this labour of love.
