This game was great until the last major update. You used to be able to play without parting with tons of money. To speed up I didn't mind spending a few quid here and there, but now the tasks are all designed to push you to spend and upgrade too many cards. The goals themselves have all gone up, such as "collect 10 or 20 cards" to "collect 85 cards" (!). Real shame as this was a great game until they got greedy. Spot the irony
