I have been playing this game for over a year (nearing two; one of my favorite games). I figured I would give some feedback/suggestions.
Unit:
Chariot - 45 wood, 5 clay, 30 food - Workshop (Creation Center) - High Speed (10 - 15), low damage (2-4), low defense (1 - 4)
Elder - 4 wood, 25 food - Palace - Low Speed , Medium Damage [carries a stick], Low defense (more on them later). Will not be attacked by enemy units, do not count towards society survival.
Buildings:
Rotatable Buildings
Switchable Building [Variants]
Change Furnace name to Metalworks/Metal Workshop
Capturing Enemy Town Centers (rather than destroying them; more on this later)
Game modes:
Conquest - map that is 4x the normal size, has four enemy holds, enemy "factions" upgrade their units (metal equipment) and expand their territory, capture all holds to win
Miscellaneous:
Savable Sessions (Single player; I often like to look at all of my work that I done in a session or see what tactics I used)
Capturing Enemy Holds - Destroy all buildings [excluding/including the Town Center; more on this later]
Intermediate Difficulty for the Alpha Mission - Beginner to Experienced makes a bit too much of a jump (it is always a gamble whether I will make a huge victory or flop right at the start). Putting in an Intermediate Difficulty (between Beginner and Experienced) might make the game feel a little less too difficult for new players.
Destroy all enemy buildings to win rather than just destroying their Town Center. I usually like to make a massive army and then raid my enemies hold. I feel a small bit disappointed that I cannot see the full battle go on.
Connecting [some] Ideas Together:
As I have said Conquest would allow us to capture holds; one way of doing this would be sending our Elders to their Town Center or Palace; where negotiations can be reached (conflict/war will still happen [like normally], however).
The negotiation feature would allow us to use their Town Center as a backup to our own (if we are invaded) once we have captured their hold. This is can be a double edged sword given that we do not place down our enemy's Town Center(s) therefore it could be in a very profitable spot or we can use it as a backup.
Hopefully you enjoy the ideas that I have given! I have been wanting a large scale battle/conquest mode for this game since I first played it (I know I could play Multiplayer, but I am more of a single player type of person).
