If grand strategy is your jam, pick this game up for sure. It hasn't been on sale for half a decade. This is a great game. I am very pleased to administrate my fiefs and conquer in the name of my master. Betray my master and strike out on my own? Why would I do that when my master is graciously allowing me to use his armies to capture castles for myself? Besides, he really gives me a lot of headpats when I cause the defection of an entire House to my clan. You can really feel Shibusawa's passion for the Sengoku Jidai period. I only ever played the SNES versions before, and this somehow carries the spirit of the gameplay through. I see that other people have their nitpicks, but this is really just very compelling for a grand strategy sim. The citybuilding and district placement aspect is a fun puzzle on a per-castle basis, and also forgiving because the districts keep their 'upgrades' even if you rebuild them to a different type. The combat is streamlined compared to something like Shogun 2 Total War. Overall I rate it five rice paddies and four tea caddies.
