Similar to what other recent reviews have said, this was a great game that has turned into a horrid one. You collect units and level them up through random draws. They increased the levels from 15 to 150, stated the amount of resources required would not change, and then instead *raised* how much you need (nearly double for the best units). The game was great, slow and steady, but now it's just a meaningless grind for anyone who isn't a heavy spender. Would heartily not recommend, now.
