EB has alot of deph. The inner struggles of MTW can be simulated in EB with the trait system.

Tribal affiliation, ethnicity, city of birth, class, ambitions, beliefs, etc. MTW2 could bring back the loyalty of your Knights/Vassals, but even that isn't as complete as EB's traits. This General is disloyal, but why? What does he want? What does he believe in? Why can't he be at terms with the King? You just won't know. Could it be that he is from a rivalling family and believes in ruthless conquest and colonization instead of the benign and liberal rule of your enlightened despot King?

Characters in EB are alive, if you could load them in a holo-deck and the computer interpreted the traits into the hologram's programming they would be perfect immitations and more complete than Voyager's doctor.

We don't know yet, but if it seems possible to port EB over to MTW2, if there are more advantages than disavantages, more to gain than to loose, it should be done. I can't imagine how delicious it would be to have the Loyalty-revolting of MTW2 with EB's trait system.

Talk about tribal rivalry, instability, fragile unity. It's the Barbarian faction's wet dream.
