Some questions (Wall of text, you've been warned)
Great job on E:FE, btw. However, I find myself with several questions that are not apparent using the Hiergamenon and manual.
Influence i.e. diplomatic currency is not covered in the Hier, and not explained anywhere in the game until you see it up for trading. (Is this intentional?) An excellent game concept candidate for a Heir entry. Please explain the methods of acquiring diplomatic currency, and if it has any use outside of buffering trades in your favor. In GalCiv2 influence affected income and perceived might, and if this currency is the same that would impact my trade decisions.
When I conquer a city, it has an occupied unrest penalty. This is good and right. However, this ALSO isn't discussed anywhere in the Hier. Does this penalty fade over time? Is the value of the penalty related to the size of the city I have taken? An entry explaining this game concept mechanic (Occupation) would be valuable. Then I might know if the intent is for me to raze it and start over, or if holding it for a certain period would be worthwhile. Could someone in the know please explain occupation penalties in more detail?
When I select "upgrade automatically" for a unit design, are only mundane weapons considered for this? Does the "Upgrade automatically" need 2 buttons, one for mundane and one for magical weapons? A prime example of this is basic spear, then unlock of the ice spear. It will not adopt this weapon as the updated design, but rather kicks up when the boar spear is researched. Since the game uses the rock paper scissors of mundane offense vs defense vs magical offense this forces manual unit upgrade redesigns when clearly that isn't the intent.
So this is not a question but... The Kingdom report says I can "Voyage upon Epic quests" and there are other references in the game to the older beta model of having to "unlock" quests of increasing difficulty via research. While I understand that under the hood (in the code) you likely just flagged everyone with "epic unlock complete" so that players could choose to bite off more than they could chew... the reference to quest unlock level in the current game engine is no longer required, I believe.
On a large map with dense champions, I only found 1 starter champion, 1 Level 5, 1L7, and 1L9 champion to recruit. Was this champion density typical or did they get eaten by roving monsters? The density of materials, and shards seemed about right. The other possible alternative (they were defeated by the opposing faction) was unlikely since I scouted him out early and it was hundreds of turns into the game before he crossed the map center in force.
The game is more polished than many I've bought in it's current state (I'm looking at you empire: total war!) and I am looking forward to it's mature patched state. To Brad, Derek, and the rest of the Stardock team, Thank You. I'm 9 hours into my current game and trying to muster enough armies to plug all the holes in the front lines at once, while responding to all the monster rampages in my backfield, has been incredibly entertaining.
