Game mechanics. Population and funerals

In «Diplomacy is not an option» population growth is due to the arrival of people in the city. The number of people coming to the city depends on the level of the Town Hall. (The higher level of the Town Hall, the more people come per unit of time). Your citizens may die of old age, from various diseases or be killed on the battlefield. In order to avoid epidemics the dead must be buried. Another type of workers – Gravediggers, are specialized in searching and burying the dead.
Some of your enemies have ability to resurrect the dead to increase the size of their army.
Also, if Player destroys the cemetery himself, the dead will rise to have their revenge and bring havoc to the city.
