A clever strategy for capturing high level valleys is to allow your enemy to capture a high level valley first. Then you attack it and capture it after he recalls his troops. For example taking a level 10 valley will require 20k troops or more. However if you wait for an enemy to take a level 10 valley then you try to take it from him, you might be able to take it with only 1 troop! You can only do this if you are out of beginner’s protection.
If you attack a valley or flat and do not have the slots available to capture it, you will still be able to loot resources from it!
Early on it might be valuable to loot nearby valleys for resources. Just send some workers or transporters along with your regular troops and they will carry resources back. Valleys contain resources based on the type of valley you conquer.
If you raid a grassland, lake, or swamp you will bring food back with your army. If you raid a desert you’ll bring stone back with you. If you raid a forest you’ll bring back wood. Etc. If however you conquer the valley so that you “capture” it, you will not bring back resources with you. Instead you will get a production bonus at your city for producing that type of resource.
