@block56 if I wanted to pay for a game I'd go somewhere else and this system is designed to milk players for money rather than give us a good product. But if you like giving them money go ahead.
Tried Urban Rivals.
Not as fun.... Play a card add pills and click... Strategy wise I'd say Urban has more potential but having to pay real money to get a pack of digital cards sucks is just about as worse as getting a real pack of cards, except its more useless.
