One feature I would like to see in STW2 is essentially a continuation and enhancement of the technology tree introduced in ETW/NTW, except for characters. I would like for my Daimyo and his heirs to study at universities to improve their governing skills, study at budhist temples/churches to increase moral virtue or righteousness, study the art of war and combat with a warmaster, study self defence with a Karate Master to improve personal security and improve the chances of surviving an encounter with a Ninja and so on and so forth. I think this would add a great touch to the campaign and make a massive difference in character development.
Conversely you could let you Daimyo spend too much time with his gilded Geisha's becoming a fop but master of court politics or send him constantly into battle without any refinement at all and become a blood thirty maniac both hated and feared.
What do you all think?
