Lets keep the economists out of this!

[Aetius the Last Roman]

One of the reasons Rome (albiet one of very few reasons) has the upper hand on medieval is the economy is harder to manage. It adds depth to the game and stops you from just going all 'Total War' on the game. Adding depth to the game may seems detrimental to those that just like to kill stuff but it does make the game better, more complex and easier to appreciate after five hours of gameplay. However that said, if people wish to just go around war-mongering I think CA should include better AI economic management.

[Samurai Waki]

Or Costum Battles...

I am entirely against dumbing down the economics for the blood thirsty masses, it adds so much to the game, if you want to kill people, by all means, play MP if the AI isn't challenging enough.
