Welcome back, jap88.
At the moment we have 4 resources; Food, Gold, Stone, and Wood. However we have various ways of gaining these resources as said on the Dawn of Fantasy website:
" Dawn of Fantasy features an entirely new approach to an economic system.
For defense oriented players who enjoy micro-managing, their entire economy can be redesigned in just a few clicks. This economic system features standards in the Real Time Strategy (RTS) genre such as farming, woodcutting, mining, etc., but also adds to the list with such amazing realistic features as crop rotation, mine building, animal herding and more. In the end, players who wish to control every aspect of their towns are able to with an innovative, easy to use system.
Players who wish to focus more on the battlefield, however, have options available as well and can take advantage of the automated economy. A complex economy is created without the need for many player choices, allowing the player to focus more on the battle at hand."
As well as Corpse Looting, which we have more information as said here:
"Dawn of Fantasy implements a unique "looting system" allowing players to recover the cost of dead units. This feature was created to reward victory as well supporting the losing player.
After units have been killed, they will be open to looting by any player. This loot is converted back into the the specific components that were used to make the unit. While the total cost of a unit will never be regained, looting offers losing players the chance to regroup and quickly rebuild their army while letting victorious players quickly eliminate their opponents."
