I have been playing Shogun II alot & think it would be cool if I worked towards a mod which is along the same theme (medieval Japan) but it is fantasy, on another planet with a culture similar to earths medieval Japanese, hopefully this would allow for more flexibility in factions (clans), the map & other various components.
I think this map from GiGantuses map collection would be interesting

I would probably have the same units as in shogun II in this but they would not be "generic" (unit cards) for all factions, like in mtw2 they would be faction specific
important I would eliminate multiple turns to recruit ( most annoying) & I would greatly lengthen the game (way too short in Shogun II)
