I'm editing my review again-I'm getting annoyed with the AI's ridiculous advancements after only 3 moves, they already have Knights?! Certain tribes I just cannot play on Alliance. Utterly ridiculous. Im trying to get equal stars among the tribes but some of them I just canNOT make any advancement. Even tho I've purchased their unique unit! I'm still really frustrated and getting burnt out that these new tribes can only be purchased with in-game gems!!! Grrr!!! You make it impossible! Giving up
