I've claimed 41 territories so far, so I'm doing good. I think my hero's up to level 20. But the last couple cities I tried to conquer ended in disaster. I slowly build up my army, keeping them close to my towers, protecting my buildings, when the enemy hero comes along and totally annihilates my entire army with one spell!!! Argh! I'm not sure how you're supposed to get around this, but it is rather discouraging and not terribly much fun. :( I guess I should just avoid those cities until I'm more powerful.
