Own FoF, CoG, and CoG EE. Will enjoy CoG EE more when minor problems sorted out.
Detailed combat in all 3 is the best I have encountered in all the strategy games played. I used to rate the Total War series quite high but they fail miserably when it comes to diplomacy.
I find the development of province resources somewhat slow and tedious in CoG EE, especially with regard to textiles as the production of quality military units depends too much on textiles, and by the time one has one's military units up to a high standard the game length is virtually over.
How about game events which boost production significantly, or when one captures a province there is a stache of resources one obtains ? Also Terms of Surrender could include a demand for certain resources from a conquered nation.
