Fortunately for the Kohan, you are Immortal Sovereigns. You don't actually die, you go back into a gold amulet like a genie back into its bottle. Well, that's the story anyway. I reckon most people buy RTS games for reasons other than the story, though, so I'll move on to the building and fighting. As the genre demands, the game is inevitably focussed on building an economy, and fighting a war.
Towns are a single economic object.
That's right - not individual settlers, but a company of settlers. You won't be building individual townsfolk to chop your wood, grow your grain and take out your trash in this game. In fact you won't build any individual units. Instead, towns allow you to create companies. Companies consist of four frontline troops of like type, two optional support units, and a captain.
