1/5 stars until they figure out a pricing structure that wouldn't bleed the player base dry. It's the most insane pricing structure I've ever seen for a game of this type--3 bucks should get me basically every item in the game, not less than one pack of cards.
Seems my comment was removed: The game, while somewhat interesting, seems solely interested in making you spend as much money as you can before you actually get enjoyment out of it--you're limited to x number of games at a time for the campaign (preposterous as games are extraordinarily short), packs are expensive (unless you pay for war bonds!)
I wish there was a way to give this game less than 1 stars for all the pay to play BS. The game isn't nearly good enough to dump money into, but the game is so heavily favored towards dumping tons of money into it to get any sort of basic enjoyment out of it that you basically can't play it for free.
