Hi. I think this could become a rather interesting discussion that can go on for quite some time . Obviously it's all in theory as we don't know for sure if there will ever be MnB 2 (projects and studios can get cancelled these days) or cRPG 2.
Personally, as much as i love variety and different cultures ( i.e. japanese, chinese etc) i think after all i'd love to see the new cRPG in a more or less strict setting, taking Medieval 2 :Total War as an example (or Crusader Kings). So~ 10-15th century, covering most of the known world of that time (muslims of middle east,spain and north africa, pagan nomads, byzantines, europeans, russia) with the exception perhaps of India, China-Korea and Japan (different theatres of warfare, except for maybe their relations with the Mongols) , basically just look at the maps of Crusader Kings or M2:TW.
I think that kind of setting will provide more than enough variety in gear and cultures to pick without making it look too chaotic and surrealistic , like some kind of a Deadliest Warrior parody.
Now don't get me wrong , i'd love to use a nodachi or play as a legionairee from time to time, but i'd rather wait to do it in some other great mods .
So what do you think ?
