Great game!!! Just lacks utility.
First of all I gave it a 7!!! Yeah! Right? Sad part, X[ is you could of had a 10. Like I said in the title is that you have utility problems in your game, others have mentioned it too. I know I'm a new user like wow just made an account.
"Just for your game btw"
Anyway though, I'm going to try to list all of the problems right now. Because lets be honest if you can fix these your going in the right direction, at least for me.
The Utility is the games biggest problem. It covers pretty much 99% of the problems or 100% in my opinion. Either way. Lets list what these are.
Trading
I love the trading system, although along with someone below me it might be a little overpowered. I just built like a cajillion Lumber Mills and then sold my lumber for lots of gold to buy like 18 Battalions of Knights/ Sun Clerics.
The other problem is of course the fact that it takes so long to trade. I honestly had such a surplus of Lumber to sell for Gold that I just taped down my mouse and left. (Totally upsetting!)
Troops:
Buying troops yet again was another problem.
(Once again the tapey mouse maneuver!!!)
Also I feel that there should be a sell troops option, maybe for a greatly reduced amount. (Not like you can't be like hey mister troop GTFO) Sorry but I'm OCD and I'm sure others are too, I like multiples of 5.
Lastly though is the information on troops don't offer the best well INFO. You said that some of the fun was figuring out which units worked together. Only problem is you didn't exactly tell which ones worked best together. Besides "Hey he is bad" "Hey he hates baddies". More information like "Provides cover for your melee units with their smoke bombs" - granting a higher defense to all melee units. Or "Hates anyone of the magical nature, nothing good ever came from their twisted powers" for the Sun Cleric, maybe making an event where sometimes they fight against each other killing some off when they are put in a quest together.
Battles:
Just not enough information. I found myself losing all my troop many a time because I thought I had enough units and the right items heroes and such to take the adventure. Additionally you could of probably provided the option to do multiple adventures at once, I mean why allow someone the option to choose how many of your troops to send if they can't be used somewhere else. I mean the more the better chances of survival.
That is all I can think of now but I think its a good start. Try getting all that in and this would be a great game. INfact if you can't or are not willing to go back and edit these features into this game then I would be very happy to see another game much like this one or the same with a different story.
GREAT GAME !!!!!
