Oh boy,
I never even dared to try a legendary Shogun II campaign, but apparently, some don't deem legendary diificult enough and impose extra "house rules" upon themselves.
One of these slightly crazy friendly neighbourhood daimyo's is the glorious Maltz.
You can read about his endeavours with the Shimazu clan in THIS THREAD.
And it seems like Shimazu is the flavour of the month, since one of our newer members, Arekkusu (welcome ) is also trying his hands at this faction. You can follow him in THIS THREAD. It's his first campaign ever, so feel free to offer him some good advice (after which he will gently chop off your head to add to his growing collection ).
