I would give 5 stars if not for the constant push to make in-game purchases for ridiculous prices. I really enjoy the game. Game play is excellent! But I am faced with two or three 3/4 screen ads to purchase in game supplies for (usually) $49.99 or $99.99 every time I enter the game and after every battle! Update: I've downgraded my rating to 3 stars because I'm now constantly at a disadvantage playing against players with tanks only available if you're paying $8/week for the premium game.
