Well, Rome: Total War graphics for battles, sentient AIs and a hoburg in every box!

What? It's a "Wish" list.

On the more realistic side...

D2's magic system in general is ridiculously awesome, but the handling of the more mundane aspects of empire building is..lacking, to say the least. Static populations without a growth scale? That's just silly.

Migration and population growth could be factors. Bad luck could cause migrations to less accident-prone areas. That could be a real balance to the luck scale.

The different racial and cultural populations could be a factor. Caelians displacing lizardmen? Neat! And each population would have its preferences. That may be a bit more work than it's worth, though.

Some more abilities for units, especially generals. Strategoi and similar units could give big bonuses to morale.
