This is what I have so far, but of course it needs to be greatly expanded.Combat System:There are 3 basic types of units: Infantry, Cavalry, and Archers (Siege and Hero are not basic types)Infantry are better against CavalryCavalry are better against ArchersArchers are better against InfantryAll weapons in the game deal one of three different types of damage: Blunt, Pierce and Slash. Hammers would do blunt, axes would do slash, most arrows would do pierce, etc.Units can be upgraded with certain armor and weapons that make them more resistant to a certain damage or increase the potency of a certain damage they deal.Magic System:Each player may choose one circle of magic to study, and can choose two others later as they progress. Spells range from battle mages casting incantations in combat to world-wide effects that send a great plague of locusts on an enemy empire. Each circle is divided into 3 arches, each of which specifies a certain aspect of this circle. Each circle has a single world-wide and immensely powerful spell that takes much time to prepare through intense ritual and exotic ingredients to focus magical power. Each arch has lesser spells that have considerably less effect, yet can mean the difference between victory and defeat in war. For example, if a vast enemy army is about to cross a frozen river, cast the spell from the Flame arch to melt it and slow them, giving you time to muster your defenses.Technology:There are many different solutions to the same problem in warfare, and players are rewarded for being creative in their arsenal of weapons they choose. The world is deep with many precious metals, and steel is by no means the strongest metal one can forge. Ores and metals are randomly distributed across the world, and so setting up more than a few mines is no doubt a good idea. Experimentation also plays a role, and players are encouraged to think beyond mere catapults and siege towers and think of things far more unique and new.Cities:You begin with a single small city at a location you may choose, and generate a revenue of gold and resources every day. What resources you get depends on the environment the city is in and any nearby mines/farms/lumber fields you have. When you have the resources and money needed, you can establish a village somewhere else in the world. As with Starscape, villages have varying stages which influence how much gold they produce every day and how much of a military population it can support.I'll add specifics later, but for now I merely wish to know if anyone is interested.
