I remember that in mtw u could start your campaing from different starting positions according to the era u chose.For example the byzantines was a huge power(easy campaign) in the early era having asia minor,balkans and south italy.in contrast in the late era they had a much more difficult start only having 3 regions(i think:)
Wouldnt it be nice to have that in m2tw?
I think that would give a great incentive to play the same faction again
