Hello, I´m a german gamer, and so my english is not very good.
But i had seen that you can only pay with Paypal or Creditcard. I have nothing of both. Shure game card is also an option, but i come from the game World of ********, and in Germany is it possible to pay by "Lastschriftverfahren" also called "Bankeinzug".
For me is this much better than buy evry month an gamecard. Perhaps this is an Option to integreat it in the payment.
