it is a bit more heavy because EAEM has some advanced campaign and battle features, night battles also. I used RS campaign map textures and mini mob for campaign map detailed ships and vagons on roads, also, campaing map armies are much more detailed, solo armies and generals have more detail model and spear, shield and sword in hand etc.

as for the changing of region city caps, i suggest you go to TW center or here if possible to modding guide's.
