Personally would love to see a crysta card too, but just adding paypal would be great too. Right now it does seem to be accepting my card, but I have had trouble with SE's payment system accepting that same card in the past so I'm not happy about it being my only choice right now outside of game time cards, which I don't want to use because of the limitations of only being able to purchase game time.

They have said that they're working on adding paypal in the future, but haven't given any timeline for when it will be added.
