Edit: Wadirum ruined this game for me! It's so massive, it should be 2 planets. The size of wadirum makes phones/tablets lag like crazy. The expansions are incredibly time consuming and never ending. I love this game! 4 stars because quite often, I cannot see my character. The camera angles are not the best. It's had to see what's attacking you. Like everyone said, you get ads for every thing you do. Expand, ad. Travel, ad. Upgrade, ad. Everything you do gives you an ad.
