Hōjō Tokimune! Now that's a character choice I don't think we've ever seen in a game before. Very interesting. He was a fairly important figure, though, so I'm glad to hear the game features him instead of the usually Ieyasu/Hideyoshi/Nobunaga.
I haven't played a Civ game since Civ 3 back in the day. More than any other game, that was the one that every single time I sat down to play it, I would almost instantly lose hours of my life. I don't know if I'm brave enough to play any of the modern versions.
I was reading about him and looks like he was reigning with iron fist. The game also features him saying this " Hello, I am Hojo Tokimune of Japan, a humble disciple of Bushido. " I love playing as Japan other than China as it's always a challenging game. Maybe you can pick it up again haha although there's a meme saying "one more turn" which is kinda true. This is why I only play 250 turns rather than 500 turns that I tried and was taking more than 9 hours of my time.
