FE is really good game! Well done Stardock!
I think that current version is really well polished and balanced. Please Stardock, make all changings carefully, becase you have found the "fun" element
Suggestions:
1) Is there any limit on the city "length"(how far from city center i can build)? If no, maby you should add some limit, because all my cities now 1 tile width and >5 length.
2)All the bandits are the same (Bandit + wolf), it should be variety.
3)One of my cities was destroyed by single spider! Maby when the city is captured by low-intelligent animal (spider, wolf, ect.) it must loose some population and some buildings, then animal will "forget" about the city for some time. It looks ridiculously when single spider destroys huge city with >7 improvements.
4) Please, add a button "remove enchantements" on the city screen (same for champions).
5) Show more info on mana when mouse_over the mana indicator
6) Show the caravans separately from troops (at the left part of the screen).
