Its ok
The Game was OK at first, as i was playing threw it. But after a while, it started getting very repetitive and boring.
Making more then three armies didn't seem necessary. And Placing an occupying force was just a huge waste of money, and since you cant get them back, seems to make the point moot. Which brings me to another point, perhaps i didnt play long enough, but i never saw a way to produce iron other then killing your enemies. its a massive hindrance since i cant upgrade my units and tech without a lot of it.
The heros are also far to generic. While your other, minor units can get inpressive upgrades, your heroes dont change at all, aside from a damage and health boost. A change in appearance and/or powers would be nice!
Aside from that, i might suggest having more upgrades around bolstering unit stats, out of combat abilitys, and more units in general. Increasing the healing abilitys of the clarics would also be a huge plus.
Other then that, you have to do something about being mobbed by the enemy. I was lucky that most of my guys would survive a series of fights against two, or even three enemy's charging them at once. I didnt have the money to remake the units that i could have put towards a new army.
