Gameplay is fun, but the game keeps teasing you with cards that you’ll only get if you are willing to invest serious money in this game by buying card slots, which is frustrating. You’ll end up playing more hours than the ones for a chance to get a couple of hero points here and there, which are not nearly enough. The only option to back up the game is through Facebook, which I don’t use, so I find that frustrating. Bottom line, don’t get too attached to the cards the game teases you with, or you’ll end up very poor in real life
